Abstract :
An efficient finite-element method (FEM) is presented in this paper to calculate the bandgap information of photonic bandgap (PBG) materials. A uniaxial anisotropic absorber is used to enclose the computational domain of the finite-element method. The presented method is very efficient in the bandgap calculation, which is essential for the design of various practical applications using PBG materials.
