Abstract
The electromagnetic radiation of multilayer boards due to power-bus noise is investigated for an idealized rectangular structure. The derivation of the far field is based on the field equivalence principle, using a lossy cavity model for the required boundary electric field distribution. The maximum electric field is studied within the frequency range 30 MHz-1 GHz. A parameter study shows that the distance between the planes is one of the most effective means for lowering radiated emissions.
