Stabilization of numerical methods for the time dependent magnetic or electric field integral equations

Viable approaches to the modelling and numerical computation of the scattering of pulses of electromagnetic energy from a perfectly conducting obstacle, of arbitrary shape, and dimensions not exceeding some number of pulse widths, are based upon either integral equations or Maxwell´s (differential) equations. The relative merits of these two approaches are examined by Miller (see IEEE Trans. Antennas Propagation, AP-36, p.1281, 1988). The author examines solution methods based upon the time dependent forms of the magnetic field integral equation (MFTE) and the electric field integral equation (EFIE). The latter applies to open or closed bodies, whereas the former applies to closed bodies only
