Rotationally invariant bianisotropic electromagnetic medium

Ludek Klimes


We determine the general form of the rotationally invariant constitutive tensor of a bianisotropic medium. In the coordinate system attached to the symmetry axis, the rotationally invariant constitutive tensor is described by twelve parameters. It is thus described by four additional parameters in comparison with an uniaxial constitutive tensor.
