✦ Synopsis

There are a number of ways in which external radiation and scattering problems can be reduced to integral equations over a surface. Often there is a discrete set of wavenumbers or frequencies for which the solution I:O these integral equations either does not exist or is not unique. In this paper we will review many of the methods for handling these nonexistance or nonuniqueness problems and will compare the accuracy and efficiency of several of these methods.
