Abstract
We propose a new technique to solve the integral equation for wave scattering by an axisymmetric inhomogeneity using the conjugate gradient (CG) method together with the fast Fourier‐Hankel transforms (FFHT). The method uses fast Hankel transform (FHT) and fast Fourier transform (FFT) requiring only O(N log N) floatingpoint operations per iteration and O(N) storage. © 1993 John Wiley & sons, Inc.
