In this study, we address the design of a pair of metamaterial surfaces capable of maintaining out-of-phase reflection coefficients over a wide frequency band. Our design is based on the genetic optimization of configurations composed of gangbuster-type frequency-selective surfaces laid on thin metal-backed dielectric substrates. An application example involving Bragg-scattering suppression in strip arrays is presented in order to assess the performance and to illustrate potential applications toreduction/control of radar cross-section signatures.

Abstract

In this study, we address the design of a pair of metamaterial surfaces capable of maintaining out-of-phase reflection coefficients over a wide frequency band. Our design is based on the genetic optimization of configurations composed of gangbuster-type frequency-selective surfaces laid on thin metal-backed dielectric substrates. An application example involving Bragg-scattering suppression in strip arrays is presented in order to assess the performance and to illustrate potential applications toreduction/control of radar cross-section signatures.
