Abstract :
In this paper, the electromagnetic (EM) field from a multilayer PCB is characterized using an equivalent dipole model. Here, the moments for the dipoles are computed from the EM information extracted in the near field of the PCB. These dipoles are modeled together with their images over a finite ground plane. In addition, passive dipoles were included to emulate the effects of the induced currents at edges leading to diffraction.
