A system of time dependent integral equations are derived and then are analytically demonstrated to be capable of treating scattering by a dielectric interface. A finite difference method is demonstrated to be capable of determining the fields scattered by an obstacle having an edge, by comparing a numerical solution to a canonical solution for scattering by a perfectly conducting wedge. Both methods are applied to the dielectric platform which has both a dielectric interface as well as an edge. The results obtained are in close aggreement and chosen to generate production data for ATLAS I related parameters by employing the finite difference method however, this should not be taken as an endorsement that this method is always preferable. As part of the investigation problems are identified for which either method would be preferred. Finally, time dependent plots of the electric field at points in the working volume are presented that show the amount of distortion caused by the platform.
