Characteristic of 2D Triangular Lattice of Photonic Crystals forMicrowave and Photonic Devices

摘要

The object of this paper is to study the fundamental characteristic of the 2 dimensional triangular lattice photonic crystals. The structure we studied consisted of a periodic array of dielectric rods in a dielectric slab. This structure has a certain forbidden gap which can be found by solving the Maxwell Equation. In this paper, we studied the frequency independent material for finding the dispersion curves using the plane wave expansion method. For the application in microwave and photonic devices, the scattering parameters of the structure must be studied. We used CST Microwave Studio to analyze the scattering parameters and the result is discussed. We also investigated the effect of different background material.
