Abstract

This paper describes fast calculation of radiated emissions from an arbitrarily shaped printed circuit board (PCB). The radiated emissions from the PCB edge are calculated by taking into account magnetic surface current based on the field equivalent principle. The electric field at the PCB edge is provided by a fast algorithm the authors have proposed for power-bus resonance in the PCB. The calculation of radiated emission was completed within a few minutes and in good agreement with finite difference time domain (FDTD) calculation. In addition, an EMI simulation was demonstrated by using a linear macro model of IC/LSI. The calculation results were found to be in good agreement with the measurements.
