Summary:
The band Faraday effects in photonic band gaps (PBG) for the three-dimensional (3D) magnetized plasma photonic crystals (PCs) consisting of the uniaxial material with face-centered-cubic (fcc) lattices are theoretically investigated by a modified plane wave expansion (PWE) method, which the homogeneous anisotropic dielectric spheres (the uniaxial material) immersed in the magnetized plasma background, as the Faraday effects of magnetized plasma are considered. The anisotropic PBGs and a flatbands region can be obtained. The effects of the anisotropic dielectric filling factor on the properties of first two anisotropic PBGs are investigated in detail. The numerical results show that the anisotropy can open partial band gaps in fcc lattices at U and W points, and the complete PBGs can be achieved compared to the conventional 3D dispersive PCs composed of the magnetized plasma and isotropic material. It also is shown that the first two anisotropic PBGs can be tuned by the filling factor.
