All-dielectric metamaterials have an upper hand overconventional metal-dielectric composites. Due to the absence of metallic inclusions, power dissipation is negligible. The functionality of dielectric metamaterials relies on the excitation of Mie-resonance in nanoparticles of high dielectric constant. Silicon is a highly permittivity material, and the fabrication techniques pertaining to it are well understood. In this article, a design of dielectric ring shaped particle based metamaterial perfect reflector has been proposed. The reflection spectrum has been calculated for different values of inner diameter d1 (150 nm, 200 nm, 250 nm and 300 nm).
