Abstract
Photonic band gaps (PBGs) of one-dimensional (1D) ternary plasma photonic crystal (PPC) with periodic and periodic-varying structures are studied based on transfer matrix method. For 1D ternary PPC, PBG can be enlarged compared with 1D binary PPC, and the influences of plasma frequency, collision frequency and incident angle on PBG are also discussed, respectively. For 1D periodic-varying structure, both the gap width and location can be controlled by thickness varying of layers with arithmetic and sinusoidal sequences.
