【 摘 要 】

Premetric electrodynamics is a representation of classical electrodynamics based on topological conservation laws. This model predicts a covariant extension of classical theory by dilaton, axion, and skewon as copartners of photon. In this paper, we report on some recent results on skewon modification of classical electrodynamics. We present the skewon modified dispersion relation for electromagnetic wave propagation. It yields several kinds of the birefringence effect of topologically different types. The superluminal character of wave propagation and the Higgs-type effect for the symmetric skewon are indicated. We present the skewon modified photon propagator and discuss the corresponding modification of Coulomb's law.
