We apply the bymoment method to the problem of electromagnetic scattering from multiple cylinders. The bymoment method uses Green's theorem to couple the finite element solution inside and around each of the cylinders to the exterior region. This method allows us to enclose each cylinder by its own individual mesh, resulting in an enormous computational and memory savings. Numerical results for several cases are presented and compared to series solutions available in the literature.
