Beschreibung

Since the concept was first proposed at the end of the 20th Century, metamaterials have been the subject of much research and discussion throughout the wave community. More than 10 years later, the number of related published articles is increasing significantly.

On the one hand, this success can be attributed to dreams of new physical objects which are the consequences of the singular properties of metamaterials. Among them, we can consider the examples of perfect lensing and invisibility cloaking. On other hand, metamaterials also provide new tools for the design of well-known wave functions such as antennas for electromagnetic waves.

The goal of this book is to propose an overview of the concept of metamaterials as a perspective on a new practical tool for wave study and engineering. This includes both the electromagnetic spectrum, from microwave to optics, and the field of acoustic waves.

Introduction

Over the past 10 years, metamaterials have been the subject of a very extensive interest, as attested by numerous publications in both highly focused and wider public journals. On the one hand, the scientific attention finds its origin in the universal character of metamaterials. Indeed, this general concept can be applied to any physics domain involving the propagation of waves. On the other hand, metamaterials are relevant to everyday life and feed the imagination, especially with applications related to invisibility.

The project of this book was initiated during a thematic school organized by the network GDR ONDES 2451, supported by the French national organization CNRS (Centre National de la Recherche Scientifique) at Oléron from 29 May to 1 June 2012. The purpose of this event was to analyze the impact of the metamaterial approach in various fields of wave research and technologies. As a prospect, starting from an overview of the main research steps, we would like to propose metamaterials as a tool available to scientists and engineers working on the various domains related to the propagation of electromagnetic and acoustic waves. Before discussing the evolution of the metamaterial activity, let us define the metamaterial concept.

A metamaterial is an artificial structure whose dimensions are much smaller than the wavelength of interacting signals. If this condition is satisfied, the metamaterial can be considered as an average media. This media can then be modeled by effective constitutive parameters. For instance, for the domain of electromagnetic waves, a metamaterial is characterized by its effective permittivity eff and permeability This permittivity and permeability in turn describe the response of the metamaterial to electric excitation and magnetic fields, respectively. Following this principle, metamaterials appear like a new degree of freedom in the design of materials because their properties do not only rely on their basic compounds but also on the way these compounds are structured, namely the dimensions and the shape of the inclusions. Depending on these parameters, we can target unusual values of eff and µeff, which give rise to outstanding physical properties like, for instance, the negative refraction if both eff and µeff are negative. In the same manner, we can design the metamaterial structure in order to target very high or, on the contrary, near zero values of the permittivity and permeability.

One limit of this general concept lies in the definition of the metamaterial itself. Indeed, if the structure dimensions are required to be much smaller than the working wavelength, a given metamaterial loses its properties when the frequency is increased. This is due to the fact that the inclusions behave as scatterers when their dimensions are close to the incident signal wavelength. Therefore, the structured nature of a metamaterial is the first limitation of its working bandwidth.
