Abstract
The electromagnetic (EM) problems with conductive objects can be solved by sur-
face integral equations (SIEs) with the method of moments (MoM) discretization in the integral
equation approach. However, the solutions may not be valid for a wide range of frequency and
conductivity. In this work, we use the volume integral equations (VIEs) to exactly formulate the
problem and propose a point-matching scheme to solve it. The VIEs are usually well-conditioned
because they are the second-kind of integral equation. The point-matching scheme can select
current densities as unknowns so that the integral kernels are free of material parameters and
the solutions can bear a significant change of frequency and conductivity. A numerical example
for EM scattering by a conductive sphere with different parameters is presented to demonstrate
the approach.
