Numerical Analysis of Propagation and Impedance Matching in 2--D Photonic Crystal Waveguides with Finite Length

Wave propagation in two dimensional photonic crystal waveguides with finite length was analyzed. The relationship between forward and backward waves could be considered in terms of quantities like Bloch and load impedances, refraction coefficients and standing wave ratio (SWR). The main propagation features were obtained using concepts of propagation and transmission lines and theory of periodic structures.
