Time domain integral equation solvers using curvilinear RWG spatial basis functions and quadratic B-spline temporal basis functions

In this paper, a robust TDIE solver based on using the quadratic B-spline temporal basis functions and curvilinear RWG spatial basis functions for transient scattering problems by arbitrarily-shaped bodies, including tapering ones, is presented. The MOT solutions converge at exponential rate at early time and then level off at machine precision, which demonstrates wonderful stability and accuracy.
