IBC-based TDIE solver for transient scattering by coated conductors

A Time Domain Integral Equation (TDIE) approach combined with Impedance Boundary Condition (IBC) for analysis of transient scattering by conductors coated with absorbing material is developed. The IBC is considered to be dependent on local incident direction and polarization property. Numerical results are compared with the analytical MIE series solutions and found in good agreements, demonstrating that the proposed procedure is stable, accurate and efficient.
