Recent advancement in the field of optical communication has made photonic crystals to emerge as a most interesting area for research. Photonic crystal is periodic arrangement of two materials of different dielectric materials that bring about photonic band gap effect. This band gap effect could be understood by analyzing the optical properties of photonic crystals. In this paper, photonic band gap calculations are performed for two-dimensional photonic crystals using MATLAB. The band structure is obtained for different radius to lattice constant ratios and refractive index values.
