Abstract

The electric field integral equation (EFIE) and the magnetic field integral equation (MFIE) suffer from a spurious interior resonance problem for closed structures. The linear combination of the two equations can remedy this issue, and the resulting formulation is referred as the combined field integral equation (CFIE). Due to its incorporation of the EFIE, the CFIE inherits a low-frequency breakdown problem. This breakdown is manifest through a poorly conditioned system matrix and poor accuracy for some problems. The CFIE also exhibits mesh instability due to the hypersingular EFIE.
