Abstract
The plasma rising time, plasma temperature and plasma density are taken as the tunable parameters, under the isothermal hypothesis. The piecewise linear current density recursive convolution finite-difference time-domain method for magnetized plasma is applied to study the filtering properties of one dimensional tunable magnetized plasma photonic crystals with single defective layer. The electro-magnetic propagation process of a Gaussian pulse through a magnetized plasma photonic crystal is investigated. The transmission coefficients through magnetized plasma photonic crystals are calculated based on which the effects of the plasma rising time, plasma temperature and plasma density on characteristic of filtering are analyzed. The results illustrate that the filter channel can be tuned by changing rising time and plasma density and the resonant frequency can not be tuned by changing plasma temperature.
