Time-domain integral-equation based analysis of scattering from conducting surfaces including the singular edge behavior.

A method for modeling singular electric currents near conducting edges within marching-on-in-time (MOT) simulators is presented. The use of singular basis functions in MOT simulators presents unique challenges not encountered in frequency-domain implementations. Numerical results demonstrate that the proposed expansion results in accelerated convergence for scatterers with sharp features. © 2002 Wiley Periodicals, Inc.
