Quantitative Analysis of Field Uniformity in “Spring-Thunder” Bounded-Wave EMP Simulator

Abstract

The peak-value distribution of electric fields in testing area in " Spring-Thunder" bounded-wave electromagnetic pulse (EMP) simulator based on parallel finite-difference time-domain (FDTD) method on Message Passing Interface (MPI) platform is given. The experiment results are also presented. The field uniformity in "Spring-Thunder" bounded-wave EMP simulator is quantitatively analyzed. The mean value, standard deviation, and the field uniformity of the simulation and the experiment results are got. Both of the field uniformity agree well. It’s useful for the selection of the size and the location of the equipment under test (EUT) in the simulator in experiment.
