摘要

-Capacitors are sources of EM field emissions whose characterization is crucial for electronic circuits EMC. This paper presents the modeling of equivalent radiating sources of rectangular film capacitors. It presents and analyses the magnetic near field measured above plastic and polyester capacitors. The measurements are then used by the inverse method to create a radiating source model for the capacitor. The results show a good agreement between the measured cartography and the one obtained when using radiating sources model. Finally, a generic radiating model is proposed for various types of rectangular film capacitors. The generic model is validated using the measurements on a rectangular capacitor. The suggested radiating model accelerates solving the inverse method. It can be used by circuit designers to optimize the placement of capacitors on the printed circuit board to reduce their coupling with other components of the studied system.
