A boundary element estimate of radiated emissions produced by unknown sources

The paper presents a Boundary Element procedure able to predict the emission radiated by unknown sources, starting from the knowledge of the electromagnetic field in a limited number of points placed on a surface surrounding the sources. The proposed approach is tested by analyzing the field distribution obtained as a superposition of the emissions produced by four different radiating elements. The influence of the number of points on the accuracy and the possibility of simplifying the measurement procedure are finally investigated.
