Abstract The hyperbolic materials are strongly anisotropic media with a permittivity/permeability tensor having diagonal components of different sign. They combine the properties of dielectric and metal-like media and are described with hyperbolic is

Due to the rapid development of THz photonics, it became necessary to create detectors of THz radiation, which would simultaneously be high-sensitive, high-speed and work at room temperature. We demonstrate that the use of thermoelectric thin Bi-Sb f
