Enables readers to grasp the fundamentals of applied electromagnetics through a blended pedagogical approach

Electromagnetic Applications for Guided and Propagating Waves comprehensively covers both fundamentals and advanced topics in applied electromagnetics (EM) for the professional, going above the basic static and dynamic EM field theories that are covered in most undergraduate EM textbooks. The textbook introduces complex topics with illustrations of modern technologies that use the topics, followed by a simple presentation of the basic vector analysis and Maxwell’s equations, supported by many practical examples, math essays, math puzzles, and the most modern technological developments from the websites of prominent technology companies.

The textbook includes review questions at the end of each topic to enhance the students’ learning experience and outcomes. It provides the links for multimedia lecture videos and directs students to relevant open sources such as YouTube videos and lecture materials from the prestigious universities of developed and developing nations. The textbook is supported by presentation slides, a solution and instructor’s manual, and MATLAB program downloads.

Written by prolific teacher Dr. Karmakar, Electromagnetic Applications for Guided and Propagating Waves discusses topics including:

  • Fundamental theories of resonators, optical waveguides and fibers, antennas and antenna arrays, wireless systems, and electromagnetic compatibility
  • Electrostatic field theory and detailed derivations of electromagnetic fundamentals such as electric charges and Coulomb’s law
  • Applications of time-varying electromagnetic fields, covering transmission lines, impedance matching techniques, and waveguides
  • How electromagnetics has impacted our day-to-day life and how we use it in our workplace and on social media
  • Historical anecdotes and evolution of EM theory from its inception to Maxwell and Hertz

Electromagnetic Applications for Guided and Propagating Waves is an essential reference for researchers, professionals, and policy and decision makers in the fields of electromagnetics, electrical engineering, wireless communications, and defense.

Preface

Electromagnetics deals with the abstract nature of electromagnetic fields and waves and their interactions with matter. It is the most abstract discipline in the entire electrical and electronics engineering field. The theories of electromagnetics also influence other fields such as particle and quantum physics, optics and thermodynamics and so on. This textbook presents a holistic approach to the advanced electromagnetics (AEM) field and wave theory and modern applications. The uniqueness of the textbook is that each topic is supported by the most recent technological developments, analogies, similes, anecdotes and emerging applications of electromagnetics in a novel pedagogy. The chapter outlines of the book are provided in the table below. The textbook can be studied over one or two semesters in a modern university. The hours that cover the topic in a 12–14-week semester are also provided in the table. These hours are indicative.

Experimental learning is the prime to gaining a solid foundation in AEM. Each important abstract theory is supported with many examples, problems, review questions, analogies and anecdotes from the built environment and nature, enabling students to correlate the complex AEM processes with objects, artefacts and natural phenomena. At the same time, such abstract theories are provided with detailed derivations so that a beginning student can understand each step of the developed theory. Therefore, the textbook has both depth and breadth of the covered AEM topics.

In conclusion, this textbook presents comprehensive AEM materials so that when a student leaves university to pursue his or her career in the field, she or he would competently deal with the design and decision-making problems related to the technical issues of wireless and guided electromagnetics. This type of AEM knowledge and transferable skills are highly sought after in the modern industry. Therefore, this book provides graduating engineering students and experienced engineers with an enhanced learning experience and outcomes of the most recent and state-of-the-art wireless communications technologies that utilise the AEM discipline.

Finally, prudent feedback from a PhD student on the textbook:

Regarding the chapter, the abstract ideologies on electromagnetics were excellently demonstrated with the simple and real-life examples which I found the most interesting part of reading. Besides, the in-detail analysis and discussion on the fundamentals were really helpful for the readers. The final integration of the real-world applications attached to the topics is also very useful and quite relevant to the topic of discussion.

I am pretty much confident that this book will be really helpful in the field of electromagnetics which will directly benefit our groups’ present and future students.

I wish you all the best with this book and feel very lucky to assist you in this megaproject. – Shahreen Hasan, PhD student, Monash Microwave, Antenna, RFID and Sensor (MMARS) Laboratory, Monash University, 1 July 2020.

Therefore, the main motto of the textbook is to give the practising engineers and would-be practising engineers advanced knowledge on AEM and skills to solve problems associated with the state-of-the-art applications of AEM. Utmost care has been taken, and research has been performed to find the emerging and cutting-edge applications of the AEM in the range of digital design, signal integrity, biomedical, mining and geoscience, telecommunications, power engineering, electronics, signal processing, antenna technology, radio frequency identification, wireless sensors and microwave active and passive design, atmospheric engineering, remote sensing, satellite communications, precision agriculture, food safety and security, climate change, driverless cars, vehicle-to-vehicle communications, radar engineering, optical communications, defence, reconnaissance, tactical engineering and optical engineering. These vast applications of AEM and their depictions of fundamental theories enrich the textbook. Not only university students and educators but also all the decision-making leaders in many government departments and non-profit organisations (NGOs) would benefit from this book.

Acknowledgements

Monash University has a long tradition of teaching and research in advanced electromagnetics. I express my sincere gratitude to my previous and present colleagues who taught the topic at various levels and enlightened me in the subject matters. They have been great teachers and researchers in the field.

For the scholarship in teaching and leadership in education. The inspiration to write this manuscript came from Monash University. I express my sincere appreciation to Monash University, and in particular, to the Department of Electrical and Computer Systems Engineering (ECSE) for creating an opportunity for this scholarly pursuit of writing a reference book on advanced electromagnetics. This pursuit also provides an Australian contribution to advanced electromagnetism (AEM) pedagogy in the modern university.

My PhD students are the lifeblood of my teaching and research, and an inspiration for this textbook. I am tremendously indebted to their contributions in all aspects of the manuscript. Without their countless bits of help and sacrifice, patience and encouragement, the project cannot be completed. Therefore, it was big teamwork like any of my big research projects with my PhD students at my research laboratory. I have no language to express my hearty gratitude to them for their invaluable and timely contributions and their sacrifice. Trong Ho helped me from the beginning to the end of the manuscript. He was my inspiration and walked along with me without any hesitation all the time. He not only helped me to edit, draw many of the images and format many of the chapters with great enthusiasm, but also prepared the summary for each chapter. I am indebted to his unique contributions to the manuscript. Guanghui Ma took on major responsibilities for the final logistics of preparing the manuscript, including appropriate acknowledgements and citations for all figures, tables and contents, and uploading the materials in Wiley-provided OneDrive. He spent countless hours for the preparation of the manuscript and led the team of PhD students in the book project. Farah Bilawal, Shahreen Hassan, Huu Nguyen, Javad Aliasgari Mosleh Abadi, Parya Fathi, Jiewei Feng, José Gabriel Argañarás, Mahabub Alam and Kim Trinh contributed tremendously towards the preparation and editing of the manuscript. Without their help, the book project would not have come to fruition. Shahreen indebted me to write a judicious reflection after reviewing and editing Chapter 7. Trong Ho, Guanghui Ma, Likitha Lasantha and Farah Bilawal checked many of the problems in the chapters.

Jiewei Feng was so kind to do prompt simulations of a few important AEM applications in computer simulation technologies for Chapter 1. I express my deepest heartfelt thanks to Dr. C.J. Reddy, Fellow ACES and Vice President of Business Development – Electromagnetics, Americas, for his valuable feedback and for some simulation results and artworks for Chapter 1.

Introduction to the practical applications and significance of the advanced electromagnetics in our everyday life

Introduction to topics usually covered in modern textbooks on advanced electromagnetics. The basic definitions of wireless transceivers, wireless channels and uniform plane wave propagation, various transmission lines and waveguides, optical fibres, antennas and antenna arrays, and finally, electromagnetic interference (EMI) and electromagnetic compatibility (EMC).

The modern pedagogical practices in advanced electromagnetics at the university.

A design project to show the applications of the learned theories of wireless and guided electromagnetics.

Learning Outcomes

At the end of the chapter, you will be able to comprehend the following:

The contributions and significance of wireless and guided electromagnetics.

A concrete understanding of the fundamental building blocks of wireless and guided electromagnetics.

New pedagogical methods used in modern universities.

A design project that sets the foundation for the practical application of the learned theories of wireless and guided electromagnetics.

Chapter Outline

The outline of the chapter is shown Figure 1.1. First, the emerging applications of advanced electromagnetics are introduced. The chapter has introduced many interesting applications of advanced electromagnetics in modern emerging technologies that have impacted our everyday life, business practices, medical treatments, social interactions and leisure. The modes of delivery of pedagogical practices have evolved from whiteboards and overhead projectors to the multi-media based interactive teaching and learning sessions with modern laboratory facilities, and cutting-edge design projects to enhance students’ learning experiences. It is a non-trivial task to design a laboratory to enhance the learning experiences through experiments in advanced electromagnetics. Usually, radio frequency (RF) and microwave sources, receivers and measuring equipment are too expensive to implement, need specific sets of expertise and the teaching methods are too abstract for students to digest. A very low-cost innovative laboratory setup that was derived for the author’s research laboratory is introduced for advanced electromagnetic teaching. A design project of wireless energy harvesting is also introduced so that students can apply their knowledge gained from the theories learned in each topic of the textbook. Laboratory experiments can be applied in a real world, emerging and ubiquitous design project with the aid of full-wave electromagnetic solvers such as computer simulation technologies (CST) Microwave Studio™ (MSW) and Keysight Advanced Design System (ADS™). These specialised software tools are used in industry for high-end design. Hands-on knowledge and skills gained in the design project develop the graduate skills and employment readiness of learners. Besides these, the knowledge and skills developed in calibration methods and measurement using a full two-port vector network analyser are also an added advantage for the students to develop graduate skills for industrial applications. The chapter concludes with Section 1.6 Summary of Chapter.

1.1 Introduction

Welcome to the textbook: Electromagnetic Applications for Guided and Propagating Waves. Advanced electromagnetics (AEM) has an abstract nature with full of mathematical derivations, and many fundamental physical laws such as the laws of Coulomb, Gauss, Biot-Savart, Ampere, and Faraday. All these laws are well presented in a set of equations, which are called Maxwell’s Equations. Figure 1.2 shows a sketch of various laws of AEM in complex vector mathematical forms. These advanced and highly complex mathematical equations for the electromagnetic laws and hypotheses easily scare new learners of electrical and electronic engineering and physics. To enjoy this subject, you should look at the big picture of contemporary technologies that we are using in modern society, and then analyse with your mind how these technologies that use wireless and guided electromagnetics impact our daily lives. Then only you can appreciate the complex nature of the discipline and enjoy learning the theories that underpin the modern wireless and guided communications world in RF, microwave, millimetre wave and light wave spectra.

With the advent of fast Internet connectivity via submarine optical fibre networks, wireless fidelity (Wi-Fi), voice over internet protocol (VoIP),1 we are so well connected, as if we are living in a small global village. The motto of the modern wireless technological development is to provide boundless flexibility and scalability without any wires. It is interesting to observe how wireless and guided electromagnetic have impacted upon us through these emerging technologies in the twenty first century. The most advancements in wireless technologies, such as global positioning satellite (GPS) system, near field communications (NFC), google navigation, 4G/5G/5G+2 wireless communications that are packaged in a smartphone, are overwhelming. If the 1980s technologies had been used, it would require tens of truckloads of electronic equipment to match the functionality of a modern smartphone, forget about the scalability.3

Figure 1.3a introduces Internet of Everything (IoE), which collects data wirelessly from every tagged item, small or big. NFC devices in your smartphones use the radio frequency identification (RFID) technology to help create a cashless society. All are being done wirelessly. The smart cities and smart farming become a reality with wireless communications. The modern technology becomes multidisciplinary and requires engineers and scientists from all branches to work together. As shown in Figure 1.3b, a modern fighter jet is equipped with advanced radar systems with steerable antennas, many wired and wireless sensors for navigation, and manoeuvring in challenging situations.

The textbook addresses all of the emerging and burning issues of our society in the new millennium and shows how the new technologies utilise the theory of AEM to address and solve many of these problems. To make the complex and abstract electromagnetic theory interesting, the introductory chapter has briefly analysed the most popular technologies that have been impacting our lives in recent decades.

1.2 Emerging Technologies That Use Advanced Electromagnetics

Table 1.1 summarises the most popular and advanced technologies that have emerged as the mainstream breakthroughs in the twenty-first century. AEM is all about the analyses of the electromagnetic wave phenomena inside the wireless channels and guided structures. The most beautiful aspect of the electromagnetic theory is that we can perceive the three-dimensional (3D) field distributions and wave phenomena due to the electromagnetic stimuli inside any structure. That is why electromagnetic theory penetrates every branch of electrical and electronic engineering. For example, in a semiconductor device, we can analyse the microscopic level of 3D field distributions and associated changes in current and voltage at the junction of different doped elements due to changes in the terminal biasing conditions. The current and voltage establish the electric and magnetic fields4 at the junctions of the active devices, such as diodes and transistors. Likewise, electromagnetic theories become the backbone of power system analysis for high-voltage transmission lines, power transformers, and generators.
