Magneto-Optical Faraday Effects in Dispersive Properties and Unusual Surface Plasmon Modes in the Three-Dimensional Magnetized Plasma Photonic Crystals

Abstract

The dispersive properties and unusual surface plasmon modes in three-dimensional (3-D) magnetized plasma photonic crystals (MPPCs) with face-centered-cubic lattices that are composed of the core tellurium (Te) spheres surrounded by the magnetized plasma shells inserted in the air are theoretically studied in detail by the plane-wave expansion method, as the magneto-optical Faraday effects of magnetized plasma are considered. Our analysis shows that the proposed 3-D MPPCs can obtain the complete photonic band gaps, which can be manipulated by the radius of core Te sphere, the plasma density, and the external magnetic field, respectively. We also find that a flatband region can be achieved, which is determined by the existence of surface plasmon modes. If the thickness of the magnetized plasma shell is less than a threshold value, the band structures of such 3-D MPPCs will be similar to those obtained from the same structure containing the pure magnetized plasma spheres. In this case, the inserted core sphere also will not affect the band structures. It is also noticed that the upper edge of flatband region does not depend on the topology of lattice.
