The scattering of time-harmonic electromagnetic waves by perfect electrically conducting (PEC) objects can be modeled by several boundary integral equations. The most prominent ones are the electric and magnetic field integral equations (EFIE and MFIE). The former is applicable to both open and closed structures, whereas the latter is applicable to only closed structures. The EFIE is susceptible to...
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...
