Symmetric and antisymmetric constitutive tensors for bi-isotropic and bi-anisotropic media

The Maxwell equations and the constitutive relations describe classical propagation of electromagnetic waves in continuous matter. Here, we investigate effects stemming from extended on bi-isotropic bi-anisotropic media using a general approach based evaluation dispersion refractive indices. For media, specify two classes magnetoelectric parameters represented by symmetric antisymmetric tensors. three cases examined have provided real distinct indices for propagating modes, which implies birefringence. modes were also carried out all cases. anisotropy or birefringence effect, given rotatory power phase difference, was evaluated terms theory each case. orthogonal to vectors used parametrize tensors is described representing route identify kind medium examined. group velocity Poynting vector discuss energy these anisotropic media.
