Calderón preconditioned electric-field integral equation (CP-EFIE) is very efficient in analyzing electromagnetic problems with a moderate electrical size. For the analysis of electrically large problems with closed surfaces, the CP-EFIE, however, suffers from the well-known spurious internal resonance problem because both the EFIE and the Calderón preconditioner are singular at resonant frequencies...
The electric-field integral equation (EFIE) is widely used for analyzing electromagnetic scattering and radiation problems because of its excellent accuracy. However, the poor spectrum property of the EFIE operator results in a very slow convergence rate in an iterative solution. Calderon preconditioner is used to improve the spectrum property of the EFIE operator, leading to a fast convergent equation...
