A feasible approach to field concentrators of arbitrary shapes

Abstract

We propose a simple method to design field concentrators of arbitrary shapes based on Fabry–Pérot resonances. The material parameters are feasible in terms of metallic layered structures and gradient index dielectrics. The functionalities are well confirmed by numerical simulations.

Keywords

field concentrator / Fabry–Pérot resonance / transformation optics
