Nihility in non-reciprocal bianisotropic media

| description | Here we consider electromagnetic response of non-reciprocal bianisotropic materials in some extreme regimes. The magneto-electric coupling is modeled by symmetric and antisymmetric uniaxial dyadics, which correspond to the so called artificial Tellegen media and moving media, respectively. Extreme electromagnetic properties of uniaxial non-reciprocal bianisotropic materials in the limiting case of nihility, when both permittivity and permeability of the media tend to zero, and only the magneto-electric parameters define the material response, are studied. Among other interesting effects, we show that the moving nihility materials provide the extreme asymmetry in the phase shift of transmitted waves propagating along the opposite directions. Furthermore, we reveal a possibility to create an angular filter with extreme sensitivity to the incidence angle, also using moving nihility slabs. |
