A stable, PWTD-accelerated time domain integral equation solver

Time domain analysis of electromagnetic scattering and radiation problems has a wide variety of applications from nonlinear circuits and antenna feeds to electromagnetic pulse studies. The ability to model nonlinearities and to perform broadband analysis makes time domain methods attractive in comparison to their frequency domain counterparts. An integral equation framework for time domain analysis also offers a number of benefits, such as satisfying radiation boundary conditions, being dispersionless, and providing an effective method for truncating the computation domain in differential equation based solvers.
