Transformation functions from feeding point to arbitrary point have been calculated by the simulator’s external shape and the geometrical relationship between simulator and the ground, then with the waveform measured in one point, the excitation signal of NEMP simulator can be obtained, and the field distribution near the simulator can be depicted.展开更多

The method consists in comparing electromagnetic compatibility （EMC） test severities to NEMP conducted stresses. The comparison uses five characteristic criteria of the induced stresses, calculated with an analytic method. The process is based on a software named ＂SUSIE＂ （in French： SUSceptibilite a I＇IEMN ＂Impulsion ElectroMagnttique d＇origine Nucl6aire Haute Altitude＂）. Today, only conducted stresses are analyzed. An evolution is planned in 2013 to determine the equivalent vulnerability of radiated stresses and to validate the software.展开更多
