Abstract

A new method for the numerical solution of volume integral equations is proposed and applied to a Lippmann--Schwinger type equation in diffraction theory. The approximate solution is represented as a linear combination of the scaled and shifted Gaussian. We prove spectral convergence of the method up to some negligible saturation error. The theoretical results are confirmed by a numerical experiment.
