Abstract
An analytic solution to the problem of scattering by multiple spheres was given by J.H. Bruning and Y.T. Lo (ibid., vol.AP-19, p.378-90 and 391-8, May 1971). Results from this analytic solution are compared to results obtained using the generalized multipole technique (GMT), a numerical method that uses vector spherical harmonics as basis functions. The boundary conditions are imposed at a discrete set of points and the solution is obtained by numerically inverting a system of linear equations. The problem is particularly well suited to the GMT because the surfaces are very smooth
