Abstract

Two-dimensional square lattice photonic crystal with defect structure was designed by using the plane wave expansion method,the materials and duty ratio of defect structure were changed. The results show that the width of transverse magnetic band-gap is larger when the permittivity of photonic crystal is higher and the duty ratio is 30% by using MATLAB.This research provides theoretic basis for the development of photonic crystal filter device.
