摘要
The effective plasma frequency (EPF) for a one-dimensional superconductor-metamaterial photonic crystal (PC) is theoretically analyzed by making use of the transfer matrix method together with Bloch theorem. The EPF in a PC is defined as the lowest frequency at which an electromagnetic wave can start to propagate through the PC. It is found that the EPF can be larger or smaller than the bulk plasma frequency of the superconductor. The EPF can even be zero when the suitable parameters are chosen. The filling factor of the metamaterial layer has an important influence on the EPF. If the filling factor is large enough, the EPF can keep being zero and is independent of the relative permittivity of metamaterial and the operating temperature. The effects of the thickness of the metamaterial layer, the thickness of the superconductor layer, the relative permittivity of metamaterial, and the operating temperature on the EPF are also discussed.
