Abstract
Field strength, waveform and uniformity are crucial to the validity of high-altitude electromagnetic pulse (HEMP) radiation sensitivity test (RS05/RS105) for large transient field facilities which are placed in expensive semi-anechoic chambers (SAC) usually. In this paper, we present a type of space requirements of those large transient field facilities installations in cheaper electromagnetic shielding room (ESR) by quantitative simulation analysis of the crucial factors. The field uniformity and the accuracy of guided-wave EMP simulator (GWES) in a SAC are verified by numerical cases and experiments. Time domain finite integral method (FIT) is employed to compute field data and singular value decomposition (SVD) technique has been used to extract the higher order modes (HOM). Based on the validated model, feasibility of GWES installation in an ESR was analyzed. The minimum space requirement of GWES installation has been obtained through optimization.
