P3-29: Dispersion relation of electromagnetic waves in magnetized plasma dielectric photonic crystals

Dispersion relations of electromagnetic wave in one-dimensional (1D) and two-dimensional(2D) magnetized plasma dielectric photonic crystal (PDPC) are studied, where external magnetic field is set to be perpendicular to wave vector. It is found that gap width can be effectively controlled by external magnetic field, these unique properties are not realized in unmagetized PDPC and solid photonic crystal composed of metal or dielectric material, which can satisfy the needs for dynamically controlling electromagnetic wave.
