The extraordinary mode in the three-dimensional magnetized plasma photonic crystals with layer-by-layer lattices containing the function dielectric

Abstract

In this paper, the characteristics of the extraordinary mode in the three-dimensional (3D) function magnetized plasma photonic crystals (FMPPCs) containing the function dielectric are theoretically investigated by the plane wave expansion method. In such a case, the magneto-optical Voigt effect is considered. The configuration for such FMPPCs is that the function dielectric columns are surrounded by the magnetized plasma, and the embedded dielectric columns are stacked with layer-by-layer lattices, which are arrayed with face-centered-tetragonal symmetry. The relative permittivity of function columns depends on the space coordinates. The relationships between the parameters of FMPPCs and the photonic band gap (PBG) of the extraordinary mode also are studied. The computed results show that the PBG can be tailored by those parameters. Compared with the conventional function dielectric PCs and plasma-dielectric PCs with the same topology, the narrower PBG for the extraordinary mode can be observed in the proposed FMPPCs, and its location is in the higher frequency region.
