Design of the multichannel filter based on one-dimensional defect plasma photonic crystal

The transmission properties have been investigated for the anisotropic plasma photonic crystal (APPC) with defect layer. Based on the transfer matrix method (TMM), the total transmission coefficient for the symmetry APPC with defect layer has been deduced. The numerical simulations shows that transmittance spectrums are the same as those of the general plasma crystal when the thickness of the defect layer is small. With the increasing of the thickness of the defect layer, the transmittance peak is split into more transmittance peaks called as the defect modes, which is different from the general plasma crystal. The defect modes caused by the defect layer in the APPC open up another choices of multichannel filters for EM waves in practice.
