Analysis of the photonic band gap of plasma photonic crystals with filmy structure

Abstract

Plasma photonic crystals are artificially periodic structures, which are composed of plasmas and dielectric structures. In this paper, the Runge–Kutta exponential time differencing (RKETD) finite-difference time-domain (FDTD) method is applied to study the one dimension plasma photonic crystals. From the perspective of frequency-domain, the effects of the relative dielectric constant, the plasma collision frequency and the plasma frequency on the photonic band gap are analyzed and discussed. According to numerical simulation, the results show that the electromagnetic band gaps of unmagnetized plasma photonic crystals can be tuned by the parameters. These may provide some useful information for basic theoretical study and designing plasma photonic crystals devices.
