Negative refraction behaviors in two-dimensional elliptical-rod photonic crystals in a centered rectangular lattice

It is shown that negative refractions exist in two-dimensional photonic crystals consisting of centered rectangular lattices of elliptical dielectric rods in air. These lattices can be considered as deviated structures from well-studied, strict hexagonal lattices. There is a tolerance of negative re...

Summary:It is shown that negative refractions exist in two-dimensional photonic crystals consisting of centered rectangular lattices of elliptical dielectric rods in air. These lattices can be considered as deviated structures from well-studied, strict hexagonal lattices. There is a tolerance of negative refractions to deviations of structural parameters from the hexagonal lattice, indicating certain flexibilities for fabrication process for these photonic crystals including the hexagonal one.
