More Complete Predictions of the Near-Field Electromagnetic Emissions Based on the Derived Equivalent Dipole Model in Time-Domain

Abstract

In this paper, based on a 3D time-domain near-field scanning system, the measured magnetic fields on a PCB surface at different sampling time points are presented to visualize the wave propagation. And the magnetic fields on the left and right prediction planes are calculated by the equivalent dipoles which are derived from the top scanning data, respectively. They are in good agreement with the simulated ones. This paper is a complement to our previous work to further illustrate the effectiveness of the equivalent dipole model to predict the near-field electromagnetic emissions from the PCB.
