Numerical Analysis on Coupling Effects of UWB Pulse into Computer Case

摘要

The finite-difference time-domain method is used to analyze the rule of the electromagnetic pulse (EMP) coupled to the computer case with different kinds of slots, apertures and hole arrays. The rule of EMP having different incident direction coupled into computer case is discussed. Power density in main points corresponded to slots or hole arrays is analyzed and illustrated. Some valuable conclusions are obtained.
