Analysis of Voigt effects in dispersive properties for tunable three-dimensional face-centered-cubic magnetized plasma photonic crystals

摘要

The Voigt effects in dispersive properties of three-dimensional magnetized plasma photonic crystals (magnetized plasma spheres immersed in dielectric background), composed of homogeneous dielectric and magnetized plasma with face-centered-cubic lattices are theoretically investigated based on the plane wave expansion method, as incidence electromagnetic wave vector is perpendicular to the external magnetic field. The equations for calculating the band diagrams are theoretically deduced. The influences of dielectric constant of dielectric, plasma collision frequency, filling factor, plasma cyclotron frequency, and plasma frequency on the dispersive properties are studied in detail, respectively, and some corresponding physical explanations are also given. From the numerical results, it has been shown that the photonic band gap (PBG) can be manipulated by plasma frequency, filling factor, plasma cyclotron frequency, and the relative dielectric constant of dielectric, respectively. However, the plasma collision frequency has no effects on the location and relative bandwidth of the PBG. The locations of two flatbands regions cannot be tuned by any parameters except for plasma frequency and plasma cyclotron frequency.
