EFFECT OF DISSIPATION ON THE CONSTITUTIVE RELATIONS OF BI-ANISOTROPICMEDIA - THE OPTICAL-RESPONSE

This paper discusses the restrictions that dissipation forces on the m aterial parameters and responses of bi-anisotropic media. The treatmen t is a general time domain analysis where six-vector formalism is appl ied. Energy conditions set limitations on the optical response dyadics and dyadic susceptibility kernels of the material that have to be sat isfied regardless the time dependence of the fields. This paper will t reat 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 ti me domain are discussed.
