Light scattering by magnetoelectrically gyrotropic sphere with unit relative permittivity and relative permeability [PDF]

Journal of the Optical Society of America A, 2014
An exact transition matrix was formulated for electromagnetic scattering by a sphere made of a magnetoelectrically gyrotropic material with unit relative permittivity and relative permeability. The total scattering and forward scattering efficiencies are lower when the magnetoelectric gyrotropy vector of the sphere is either coparallel or antiparallel ...

Gyrotropic impact upon negatively refracting surfaces [PDF]

, 2005
Surface wave propagation at the interface between different types of gyrotropic materials and an isotropic negatively refracting medium, in which the relative permittivity and relative permeability are, simultaneously, negative is investigated. A general
