Fast analysis of scattering by arbitrarily shaped three‐dimensional objects using the precorrected‐FFT method

Abstract

Abstract This Letter presents a fast solution to the electric‐field integral equation (EFIE) for large, three‐dimensional, arbitrarily shaped objects. The EFIE is discretized by the method of moments and the precorrected‐FFT method is then used to accelerate the matrix–vector multiplications in iterations. The resulting algorithm leads to a great reduction in memory requirement and execution time and can be modified to fit a wide variety of systems with different Green's functions without excessive effort. © 2002 Wiley Periodicals, Inc.
