Radiation pattern of a hybrid type high altitude electromagnetic pulse (HEMP) simulator

Abstract

The high altitude electromagnetic pulse (HEMP) simulators used to simulate the threat level HEMP environment according to the various standards. The electric field radiated outside the working volume may have significant impact on the nearby electronic systems. In this paper we have computed the radiated far field in time domain and electric field radiation pattern of a hybrid type HEMP simulator in θ and φ plane at various frequencies using Method of Moments. Based on the radiation pattern the orientation of the simulator can be decided to minimize the interference effects to critical electronic systems.
