  Though the method-of-moments implementation of the electric-field integral
equation plays an important role in computational electromagnetics, it provides
many code-verification challenges due to the different sources of numerical
error. In this paper, we provide an approach through which we can apply the
method of manufactured solutions to isolate and verify the
solution-discretization error. We accomplish this by manufacturing both the
surface current and the Green's function. Because the arising equations are
poorly conditioned, we reformulate them as a set of constraints for an
optimization problem that selects the solution closest to the manufactured
solution. We demonstrate the effectiveness of this approach for cases with and
without coding errors.
