摘要：

Electromagnetic wave transmission at THz in a one-dimensional superconducting metallo-clielectric superlattice has been theoretically investigated based on the transfer matrix method together with superconductor electromagnetics. The results of transmittance spectra show the existence of a cutoff frequency in such a bilayer periodic structure. Electromagnetic wave is allowed to propagate through the structure when its frequency is higher than cutoff frequency. However, it will be totally reflected at a frequency below cutoff frequency. This cutoff frequency is strongly dependent on thicknesses of the superconductor and dielectric layers, and the temperature as well. In temperature-dependent transmittance, strong oscillations can be seen at higher temperatures. (C) 2008 Elsevier B.V. All rights reserved.
