In combined field integral equation (CFIE) method for solving electromagneticscattering from conductive target with open cavity
there appear both EFIE operator and MFIE operator imposed on unknown combined sources
resulting in complicated calculations.In this paper
a equalized CFIE has been derived
in which the integral operators imposed on electrical and magnetic currents are simply same
and the computation complexity is reduced dramatically due to this single operator in ECFIE.Combination of ECFIE with multilevel fast multipole algorithm (MLFMA) can easily solve electromagnetic scattering from conductive target with open cavity.The numerical examples in this paper show the high precision and high efficiency of this method.
