On Calderón Techniques in Time Domain Integral Equation Solvers

In this paper, time-domain Calderon identities will be constructed. These identities will be used in constructing a time-domain Calderon preconditioned electric field integral equation (CP-EFIE) which can be proven to be well behaved in the regime of dense discretizations. It will be explained how this modified electric field integral equation can be accurately discretized. Numerical results will be presented that compare the performance of the proposed equation and that of the classical TD-EFIE, thereby demonstrating the effectiveness of the method.
