Abstract :
The use of a hybrid MoM-FDTD method can be effective for solutions of electromagnetic scattering and radiation problems, which are intractable for single full-wave numerical methods. In this paper we demonstrate a possibility of increasing computational efficiency of the hybrid MoM-FDTD method for obtaining broadband antenna response by employing the asymptotic waveform evaluation (AWE) technique in the MoM domain.
