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 th...

Summary: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.
