Enhanced nonreciprocal radiation in Weyl semimetals by attenuated total reflection
AIP Advances, 2021 Recent studies have suggested that Weyl semimetals were the promising materials to verify Kirchhoff’s law for nonreciprocal materials in experiment. Nevertheless, existing designs based on Weyl semimetals could not achieve perfect nonreciprocal radiation

Bragg reflector enhanced attenuated total reflectance [PDF]
Journal of Applied Physics, 2009 We model the effects of a quasibound photonic state that can exist within a substrate/metal film/Bragg reflector/air structure. The photonic state is confined as a result of total internal reflection at the air interface coupled with the effect of the photonic band gap of the Bragg reflector.

Characterisation of Biological Materials at THz Frequencies by Attenuated Total Reflection: Lard
Applied Sciences, 2020 The penetration depth of an evanescent wave in Attenuated Total Reflection (ATR) is dependent on the wavelength of the radiation utilised. At THz frequencies, the penetration depth into biological tissues is in the order of 0.1 to 0.5 mm; rendered pig ...

Tunable graphene-based polarizer [PDF]
, 2012 It is shown that an attenuated total reflection structure containing a graphene layer can operate as a tunable polarizer of the electromagnetic radiation. The polarization angle is controlled by adjusting the voltage applied to graphene via external gate.
