Single source integral equation for wave scattering by multiply-connected dielectric cylinders

The problem of wave scattering by multiply-connected dielectric cylinders is solved through the application of a single source integral equation. The formulation is similar to that of the well known electric field integral equation (which uses coupled sources of electric and magnetic surface currents), but with the particular fields defined such that the scattered field is a function only of an electric surface current which is distributed over all interfaces. Results of two example calculations with this method are compared with those from the electric field integral equation to demonstrate the increased efficiency of the single source integral equation method
