Superconductor-plasma based hyperbolic material (SPHM) and Metamaterial-plasma based hyperbolic materials (MPHM) are the plasma based composite hyperbolic materials. Using the effective medium theory, the permittivity of SPHM and MPHM has been investigated. Perpendicular and parallel permittivities, real and imaginary part, versus normalized frequency have been analyzed with variation of filling fraction of composite hyperbolic material. The optical properties of one-dimensional ternary periodic structure (1DTPS) containing Si, SiO2 and SPHM or MPHM have been studied using the well-known simple transfer matrix method (TMM) and Bloch's function. The absorption spectra of 1DTPS containing plasma based hyperbolic material have been analyzed with the variation of incident angle, electron collision frequency of plasma and filling fraction of the composite materials. By studying absorption property of 1DTPS, the absorption spectra of MPHM were found better results compared to the absorption spectra of SPHM. The calculations reveal that meta-material-plasma based hyperbolic material (MPHM) may be used to design the sensor, detector and switching applications at microwave region.

基于超材料-等离子体的双曲材料,用于微波区域的传感器、探测器和开关应用

超导体-等离子体基双曲材料(SPHM)和超材料-等离子体基双曲材料(MPHM)是等离子体基复合双曲材料。使用有效介质理论,研究了 SPHM 和 MPHM 的介电常数。垂直和平行的介电常数、实部和虚部与归一化频率的关系已经通过复合双曲材料填充率的变化进行了分析。已经使用众所周知的简单传递矩阵方法 (TMM) 和 Bloch 函数研究了包含 Si、SiO2 和 SPHM 或 MPHM 的一维三元周期结构 (1DTPS) 的光学特性。分析了含等离子体双曲材料的 1DTPS 的吸收光谱随入射角的变化,等离子体的电子碰撞频率和复合材料的填充率。通过研究1DTPS的吸收特性,发现MPHM的吸收光谱与SPHM的吸收光谱相比具有更好的结果。计算表明,基于超材料等离子体的双曲材料 (MPHM) 可用于设计微波区域的传感器、探测器和开关应用。
