Using the computer program described in Appendix for TM scattering from p.e.c cylinders, find the surface currents for circular cylinders of circumference 1.0λo 2.vλo, and 2.405λo. If possible, compare your numerical results with exact solutions. Do the results seem to converge in every case with an increasing number of cells in the models? Based on your observations, propose guidelines for minimum cell densities.
