Abstract: In this communication, we propose a novel technique based on the electric field integral equation (EFIE)-coupled Poggio-Miller–Chang-Harrington–Wu-Tsai (PMCHWT) equation to effectively analyze the broadband properties of dielectric/metallic composite objects. In the conventional asymptotic waveform evaluation… read more here.
