Abstract
Moment method solutions to the magnetic field integral equation (MFIE) are often less accurate for a given grid than corresponding solutions to the electric field integral equation (EFIE). We propose that the cause of this observation is the identity operator in the MFIE and show how regularizing the identity increases the convergence rate of the discretized two-dimensional MFIE by three orders.
