摘要：
This paper introduces a Yukawa-Calderon time-domain combined field integral equation for electromagnetic scattering by a perfect electric conductor. The time-domain electric and magnetic field integral operators are composed with Yukawa-type integral operators. The linearly combined formulation is well-conditioned when the spatial discretization is dense, and it is also free from interior resonant frequencies. Several numerical results corroborate the properties of the proposed formulation.
