Abstract
This paper numerically studies the coupling of the ultrawide band electromagnetic pulse into mines. Some typical coupling results are presented for different incident angles and distances from the antenna to the mine. In order to investigate the coupling problem, this paper studies the perfectly marched layer used to truncate the lossy boundary, and provides the distributions of the electric field radiated from the TEM horn antenna fed by the UWB signal.
