Modelling and Simulation (using MATLAB) of Silicon Carbide (SiC) based 1- Dimensional Photonic Crystal with 3 Layered Unit Cell

In this paper Silicon Carbide (SiC) based 1D photonic crystal with 3 layered unit cell are analyzed .The transmission characteristics of 3 layered unit cell phonic crystal have been analyzed by transfer matrix method and when someone construct a periodic structure of such kind of phonic crystal and compare their various characteristics such as stop band width , pass band width, centre band gap etc, by passing a particular light waves of its particular wavelength in nanometer range ,where one layer is always should be of SiC based semiconductor material. The purpose of such periodic structure is to compare the characteristics of various material combinations, when a light passes through every semiconductor layer, each layer has its own refractive indices due to this reason the different material combination shows different characteristics. This procedure able us to know the characteristics of a light wave when it goes through Silicon Carbide (SiC) based 1D photonic crystal with 3 layered unit cell.
