Metamaterial-plasma based hyperbolic material for sensor, detector and switching application at microwave region.

ABSTRACT

Superconductor-plasma based hyperbolic material (SPHM) and meta-material-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 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 to yield better results compared to the absorption spectra of SPHM. The calculations reveal that meta-material-plasma based hyperbolic material may be used to design the sensor, detector and switching applications at microwave region.
