超导光子晶体的低频光谱

Low-frequency spectroscopy of superconducting photonic crystals

A. N. Poddubny, E. L. Ivchenko, Yu. E. Lozovik

摘要:

研究了含超导元件的二维光子晶体对电磁辐射的透射、反射、吸收和光子色散规律。采用逐层Korringa-Kohn-Rostoker方法计算了光子晶体的光学性质。超导圆柱阵列的数值计算结果已被理解在一个简单的分析模型。讨论了温度和磁场对超导光子晶体光学特性的控制。超导组分密度随温度的变化特别导致透射峰的显著降低,甚至导致某些吸收峰的非单调行为。

英文摘要:

Transmission, reflection and absorption of electromagnetic radiation and photon dispersion law for 2D photonic crystals with superconducting elements are studied. The calculation of optical properties of photonic crystals is studied by layer-by-layer Korringa-Kohn-Rostoker techniques. The results of numerical calculations performed for an array of superconducting cylinders have been understood in terms of a simple analytical model. The controlling of optical properties of superconducting photonic crystal by temperature and magnetic field is discussed. The variation of superconducting component density with temperature leads, particularly, to significant reduction of the transmission peaks and even to a nonmonotonous behavior of some absorbance peaks.
