Paper Abstract

We analyze the properties of acoustic and electromagnetic metamaterials with anisotropic constitutive parameters. Particularly, we analyze the so-called Radial Wave Crystals, which are radially periodic structures verifying the Bloch theorem. This type of crystals can be designed and implemented in acoustics as well as in electromagnetism by using anisotropic metamaterials. In acoustics, we have previously predicted that they can be employed as acoustic cavities with huge quality factors and also like dynamically driven antennas. Similar functionalities are here proven in the electromagnetic domain with, in particular, an analysis of the functionality of practical devices operating in the microwave regime. Starting from our recent works on anisotropic structures and their comparison in both application fields, we present a complete discussion concerning their properties in acoustics and electromagnetics.
