A hybrid method for analyzing scattering from composite conductor and multiple dielectric objects

An efficient hybrid method of SJMCFIE combined single integral equation with the electric/magnetic current combined field integral equation is used for analysing scattering from composite conductor and multiple dielectric objects, in which, SIE can reduce one half unknowns in dielectric regions. SJMCFIE can greatly reduce the storage requirement. Moreover, Multilevel Fast Multipole Algorithm is employed to accelerate matrix-vector multiplications which can improve computation efficiency. Finally, some examples verify the validation of SJMCFIE-MLFMA, and indicate that this hybrid method is an effective tool in analysing multi-zone local coated conductor.
