Abstract :
The plasma photonic crystal (PPC) is a periodic array composed of alternating thin unmagnetized (or magnetized) plasmas and dielectric materials (or vacuum). In this paper, the piecewise linear current density recursive convolution (PLCDRC) finite-difference time-domain (FDTD) method for the simulation of unmagnetized 2-D cylindrical plasma is applied to model unmagnetized PPCs structures. A perfectly matched layer (PML) absorbing material is used in these simulations. In frequency-domain, the reflection and transmission coefficients through unmagnetized PPCs are computed and their dependence on plasma frequency, background permittivity, collision frequency is studied. The results show theoretically that the photonic band gaps of unmagnetized PPCs be tuned by the plasma parameters.
