Abstract: A hybrid method of physical optics and time domain integral equation(PO-TDIE) is presented to analyze antenna electromagnetic compatibility(EMC) on electrically large platform.General formulation and computational complexity are deduced in detail.Numerical results show that the computational cost is reduced obviously compared with classical marching-on in time(MOT) solver.The hybrid method could be effectively applied in EMC analysis.

Key words: physical optics, time domain integral equation, electrically large platform, antenna, electromagnetic compatibility, marching-on in time
