Photonic band structures of 2d photonic crystals with half-elliptical holes

In recent years, periodic photonic crystal structures have attracted much attention due to potential application in controlling electromagnetic wave propagation [1]. In this paper, the photonic band gaps in two-dimensional photonic crystal with square lattice composed of half-elliptical rods in air...
