초록

In this paper, a technique to estimate EMI source distribution on a digital circuit board ir introduced. A sensitivity analysis method is applied to reconstruct the source distribution from measured electric field data. Results from a single-layer measurement and a double-layer measurement are compared. It will be shown, from the simulation, that the use of sensitivity analysis for the EMI source reconstruction problem can be a very promising technique.
