The Rayleigh Hypothesis is a well-known semi-analytical method for solving scattering problems with complex geometries and nontrivial near-fields. Here, an alternative representation of the fields by several sources, distributed on the skeleton of the scatterer is presented, where Scattering solutions are computed with JCMsuite.
