A Comparison of the Performance of 2D Square and Rectangular Dielectric Vein Structures

Abstract

This technical report describes a computational research task performed to support continuing investigations into the electromagnetic behavior of photonic crystals. Simple dielectric vein structures are used to mimic the configuration of the photonic crystals found within the wings of the Green Hairstreak Butterfly, an insect noted for its use of photonic crystals for coloration. An earlier investigation employed a square dielectric vein structure to approximate these photonic crystals. In this case, the numerical model is improved. A rectangular vein structure is employed with two distinct values for the vein dielectric permittivity. The performance of the rectangular model is compared with that of the square model for both the Transverse Electric and Transverse Magnetic waves under mirror symmetry. The structure of attendant photonic bands is discussed.
