Broadband Metamaterials in Electromagnetics Technology and Applications

The rapid development of technology based on metamaterials coupled with the recent introduction of the transformation optics technique provides an unprecedented ability for device designers to manipulate and control the behavior of electromagnetic wave phenomena. Many of the early metamaterial designs, such as negative index materials and electromagnetic bandgap surfaces, were limited to operation only over a very narrow bandwidth. However, recent groundbreaking work reported by several international research groups on the development of broadband metamaterials has opened up the doors to an exciting frontier in the creation of new devices for applications ranging from radio frequencies to visible wavelengths. This book contains a collection of eight chapters that cover recent cutting-edge contributions to the theoretical, numerical, and experimental aspects of broadband metamaterials.

Broadband Anisotropic Metamaterials for Antenna Applications. Broadband Low-loss Metamaterial-enabled Horn Antennas. Realization of Slow Wave Phenomena Using Coupled Transmission Lines and their Application to Antennas and Vacuum Electronics. Design Synthesis of Multi- and Broad-band Gap Electromagnetic Metasurfaces. Temporal and Spatial Dispersion Engineering using Metamaterial Concepts and Structures. Broadband Performance of Lenses Designed with Quasiconformal Transformation Optics. Broadband Chirality in Twisted Metamaterials. Broadband Optical Metasurfaces and Metamaterials.
