摘要
利用传输矩阵法研究了含特异材料的一维超导光子晶体的带隙特性.研究表明,这类超导光子晶体同样具有由传统的电介质材料构成的超导光子晶体一样的低频带隙,且在一定的参数下该低频带隙可以相当宽.但在一定的结构参数下,这类超导光子晶体同完全由传统的电介质构成的光子晶体一样不存在低频带隙.还就超导光子晶体的偏振特性、光子晶体结构参数及环境温度的变化对光子带隙结构的影响进行了研究.
Bandgap properties of one-dimensional superconducting photonic crystals containing metamaterials are investigated by the trans- fer matrix method. It is shown that the low-frequency band gap can also be present in this superconducting photonic crystal similar to the usual superconducting photonic crystal containing dielectric materials. The low-frequency band gap can be widened considerably when the suitable structure parameters are chosen. However, in certain structural parameters, the low-frequency band gap can not be found in this superconducting photonic crystal just as in one-dimensional dielectric-dielectric photonic crystal. The polarization properties and the influences of the operating temperature and the structure parameters of superconducting photonic crystals on the photonic band gap are also investigated in this paper.
