Abstract
Creating an equivalent field source is an efficient method for predicting radiated emissions from IC structures. In this paper, the maximum radiated emissions for a heat-sink/IC structure is predicted by creating an equivalent source from the measured electrical field (E-field) in the gap between the heatsink and IC. The E-field is detected by an E-field probe made of an open coaxial cable coated with absorbing material. A numerical model is built in the computer simulation technology microwave studio to obtain the maximum radiated field, where the measured E-field is used as a source to excite the heat-sink model. The evaluated maximum radiated field is in good agreement with the measured value; the error is within 7 dB up to 40 GHz for the source with phase, and 7 dB up to 10 GHz for the phaseless measurement.
