An Experimental Investigation of the Parallel-Plate EMP Simulator with Single-Pulse Excitation

The properties of the parallel-plate Harvard EMP simulator (HES) are studied in the time domain under single-pulse excitation. The behavior of the HES is observed through three windows: the voltage at the driving point, the current and charge densities on the surfaces of the top plate, and the electric field between the plates in the simulator. In order to eliminate the systematic interference which can be quite severe, a new technique of "dual measurements" has been developed and more accurate data have been obtained. The measurements have been interpreted with the help of knowledge acquired from earlier continuous-wave investigations and from studies with the similar rhombic EMP simulator.
