Abstract :
Skewon-axion medium is a bi-anisotropic medium defined by 16 free parameters out of 36. A plane wave in such a medium is not restricted by a dispersion equation. Applying plane-wave equations in four-dimensional formalism, it is shown that an interface of a skewon-axion medium can be defined to produce a boundary condition which generalizes the DB and soft-and-hard boundary conditions to SHDB conditions. The SHDB boundary is self-dual, invariant in any three-parameter duality transformation.
