Abstract

This letter presents an alternative implementation of the time domain adaptive integral method (TD‐AIM) for solving combined field integral equation (CFIE) pertinent to electromagnetic surface scattering phenomena. We use the cubic spline as temporal basis function and analytically remove the rot operator from the integrals of far‐zone interactions. Furthermore, we decompose the huge 4D FFT into several smaller ones in time domain. Consequently, the TD‐CFIE can be solved with relatively littler memory and computational resources accurately. Simulation results have been presented and demonstrated the effectiveness of the proposed implementation method. © 2008 Wiley Periodicals, Inc.
