Time-Domain Calder ó n Identities and Preconditioning of the Time-Domain EFIE

An analytical preconditioner for the time-domain electric field integral equation (EFIE) has been developed. First, a time-domain operator identity that enables the construction of an analytically preconditioned time domain EFIE is constructed. Second, a procedure for efficiently discretizing this new time domain EFIE is elucidated. Numerical results that demonstrate the performance of the new analytical preconditioner are presented
