Abstract

The scattering problem for a dielectric body is formulated in terms of the electric field integral equation where the scatterer is of general shape, inhomogeneity, and anisotropy. On applying the pulse-function expansion and the point-matching technique, the integral equation is solved using an efficient procedure involving the conjugate-gradient method and the fast Fourier transform (FFT). The solution procedure runs parallel to that of the two-dimensional case previously presented by the author (see ibid., vol.AP-35, p.1418-25, Dec. 1987). Most of the work presented involves generalizing two-dimensional Green's function and operations into corresponding three-dimensional ones.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
