reads
Photonic Band Gap (PBG) materials are artificial, periodic, dielectrics that enable engineering of the most fundamental properties of electromagnetic waves. These properties include the laws of refraction, diffraction, and spontaneous emission of light. The optimal design of photonic band gaps for two-dimensional hexagon is considered. We use the finite element method to get the discretization. The dielectric function is smooth and changed by a generalized gradient ascent method.
