摘要:

提出了基于元素II型和层状高温超导体的超导纳米结构组成的特殊光学结构。计算了不同几何尺寸下的光子能带结构和光学S矩阵。这种结构产生太赫兹(THz)光子带隙,这是由温度和几何参数控制。此外,所提出的结构在所考虑的太赫兹范围内显示可控的光学反射率和透射率。根据前面的分析,计算是在层状超导体折射率为负值的特定频率范围内进行的。

英文摘要:

Special optical structures composed of superconducting nanostructure based on the elemental type-II and layered high-Tc superconductors are proposed. The photonic band structure and the optical S-matrix are calculated for these proposed structures for different geometrical values. Such structures produce terahertz (THz) photonic band gap, which is controlled by the temperature and geometrical parameters. In addition, the proposed structures show controllable optical reflectance and transmittance in the considered terahertz range. The calculations are performed in a special frequency range in which the refractive index of the layered superconductors has negative value according to the previous analyses.
