Abstract :
A simple transformation of the Galerkin inner products arising in the numerical solution of volume integral equation formulations with piece-wise constant functions is presented. Making use of some simple steps, we derive integrals of reduced dimensionality and smoother kernels, amenable to standard cubatures developed for surface integral equation formulations.
