Abstract
This paper presents an alternative combined‐field integral equation (CFIE) for conducting scatterers to surmount the nonuniqueness problem around the interior resonance frequencies. The implementation of an alternative CFIE is simplified by transforming the integrals of electric‐field (EFIE) and magnetic‐field (MFIE) integral equations to be of the same type. Through the method of moments (MoM), the commonly used Rao–Wilton–Glisson (RWG) basis and testing functions are exploited in the calculation of the alternative CFIE impedance matrix. The numerical results are illustrated and compared with those of the MFIE. © 2006 Wiley Periodicals, Inc.
