Plasma Induced Transparency in One-dimensional Duplicated Superconducting Photon Crystal

The effect of plasma layer is incorporated in the study of the transmission properties of one-dimensional duplicated superconducting photonic crystal (DSPC). The transmission and reflection coefficients are derived based on the matrix-transfer method. The influence of relevant physical parameters such as incident angle, thickness of plasma layer, plasma density, and number of periods is numerically examined on the transmission spectra for TM waves. It is shown that the Brewster-type transparent windows are generated at the angle near 𝜃 ≈ π/2 owing to the presence of the plasma layer. Moreover, it is demonstrated that the width and the position of the total transmission peaks can be controlled by the plasma density and the thickness of the plasma layer. It is also shown that as the number of periods increases, a transmission peak is divided into several peaks. It is also found that by changing the thickness and temperature of the superconductor layers, the plasma induces the perfect transparency windows for TE waves.
