Optimization of two dimensional chiral photonic crystal nanostructures

Abstract

A chiral photonic crystal (CPC) in 2D is a structure that presents the variation of the dielectric permittivity and the chirality parameter along two directions of space. The objective of this paper is to simulate and study geometric effects on the characteristics of 2D chiral photonic crystal based on dielectric material using Comsol Multiphysics 5.0 environment. The properties of Chiral Photonic Crystal are discussed based on transmission coefficient (S₂₁) and reflection coefficient (S₁₁).
