Abstract

High altitude electromagnetic pulse (HEMP) simulator is used to simulate the electromagnetic effects of exo-atmospheric nuclear burst 1]. The electric field generated inside the working volume of the HEMP simulator can be represented as the combination of the dominant transverse electromagnetic (TEM) and transverse electric (TE) and transverse magnetic (TM) higher order modes. The higher order mode distorts the wave shape of the fundamental mode. The higher order modes arise mainly due to different field component appearing in different directions, physical size of the electromagnetic systems and feeding restrictions. They can be quantified in terms of the electric field component in the direction of propagation. In this paper singular value decomposition (SVD) technique 2]3] has been used on computed and measured field data to extract the higher order modes in the working volume of the existing HEMP simulator.
