Time-spectral domain Green's dyad in a lossless half-space

Generalized formulations for the time-spectral-domain Green's dyad in a half-space are presented. The authors have modified the canonical Hertzian potential in the frequency domain to achieve exact analysis possibilities and give the equation for the electric and magnetic Green's dyad. It is pointed out that for the scattering problem of dielectric targets, the Green's dyadic function can be simplified by neglecting the contribution of the apparent charge. By using the derived Green's dyad, time-domain scattering from an arbitrary scatter buried in a lossless half-space can be calculated easily.<
