Periodic Band Gap Structure for Unmagnetized Plasma Photonic Crystals
|
Abstract:
Current density convolution (JEC) on finite-different time-domain (FDTD) method is applied to study 1D unmagnetized plasma photonic crystals.The effect on periodic band gap of unmagnetized plasma is analyzed by its periodic structures and parameters of plasma.The electromagnetic propagation process of a Gaussian pulse through an unmagnetized plasma photonic crystal is investigated.The transmission coefficients through unmagnetized plasma photonic crystals are computed ,and the periodic characteristic of band gap structure for unmagnetized plasma photonic crystals is analyzed with them.The results show that different periodic band gaps is obtained by changing parameters.
