THEORETICAL DESIGN TE-POLARIZATION ONE-DIMENSIONAL PHOTONIC CRYSTAL

Optical properties of photonic crystal structures have attracted great interest in research area and industry field because of its capability to guide and control light propagation in compact device with feature sizes comparable to light wavelength. In this paper we describe theoretical analysis and design of one dimensional photonic crystal which has refractive index ( 45.1 1 = n and 45.3 2 = n ). The program is written in MATLAB to simulate and analysis dispersions of electromagnetic waves in one dimension photonic crystal for s-polarization states. The one dimension photonic crystal has a unit cell made of different dielectric materials. The propagation angle in one medium is taken with respect to normal inside the first medium varies between 0 and 2/ π .
