Abstract :
In this paper, the hybrid CFIE-IEFIE with ILU(0) preconditioner is proposed to efficiently solve the electromagnetic scattering problems. The main purpose is to avoid the unstable phenomenon of the ILU(0) preconditioner in the solution of CFIE-EFIE. The reason for the stableness in our case is that the hybrid CFIE-IEFIE is similar to CFIE. Hence it is an efficient scheme to analyze the scattering of the structures consisting of both open and closed surfaces.
