Time-domain Green dyadics for temporally dispersive, bi-isotropic media

Time-domain Green dyadics for linear, homogeneous, temporally dispersive bi-isotropic media are presented. Complex time-dependent electromagnetic field is introduced. Approximation to the complex field from an electric point dipole in an unbounded bi-isotropic medium with respect to the slowly varying components (second forerunner approximation) is obtained. Numerical examples are presented. Surface integral equations for the tangential components of the electromagnetic fields are derived for two standard scattering problems
