Paper Abstract

In this work a novel design of an all-dielectric metamaterial perfect reflector has been proposed which exhibits 100% reflectance at a particular frequency and high reflectance in a broad range of wavelengths. This design is purely dielectric, hence, is free from resistive losses which are intrinsic to metallic thin film type reflectors. The design is compatible to on-chip fabrication techniques and can be realised by using well known methods such as optical lithography or electron beam lithography. The proposed structure can augment the performance of low loss cavity resonators, frequency selective filters, sensing, directive emission of radiation, etc.
