A modified dyadic kernel for surface integral equations of transverse-electric wave scattering by impenetrable shapes is presented. It uses auxiliary magnetic multipole components to reduce the broadside interactions between surface regions and, thus, enhance the rank deficiency of the corresponding matrix operator blocks. Its structure enables its application for various scatterer shapes and fast solver acceleration with controllable accuracy within a broad error threshold range.
