Abstract :
Photonic crystals (PCs) are widely applied in microwave engineering, antenna engineering and so on. Properties of PCs are often analyzed by the FDTD method. Propagation modes of PCs are one of the important properties. However, FDTD method cannot distinguish degenerate or nondegenerate mode due to its calculation procedure. This paper indicated that an effective classification technique of the degenerate and non-degenerate mode in the FDTD analysis of PCs using a group theory.
