Effect of dissipation on the constitutive relations of bi-anisotropic media - the optical response

In English This paper discusses the restrictions that dissipation forces on the material
parameters and responses of bi-anisotropic media. The treatment is a general
time domain analysis where six-vector formalism is applied. Energy conditions
set limitations on the optical response dyadics and dyadic susceptibility
kernels of the material that have to be satisfied regardless the time dependence
of the fields. This paper will treat in detail the resulting restrictions for the
optical response of bi-anisotropic media. Examples are given for some special
cases. Also uniqueness and equivalence aspects of constitutive relations in the
time domain are discussed.
