| Abstract: | The piecewise linear current density recursive convolution finite-different time-domain method is applied to study the filtering properties of one dimension tunable unmagnetized plasma photonic crystals with single defect layer. In frequency domain, the transmission coefficients of electromagnetic differential Gaussian pulses are computed, and under the isothermal hypothesis, the plasma relaxation time, plasma temperature and plasma frequency are taken as the tunable parameters to study the effects of filtering properties. The results are as follows: the filter channel can be tuned by changing relaxation time and frequency of plasma,while the resonant frequency can not be tuned by changing plasma temperature. |
