This paper presents an attempt to solve the problem of predicting radiated emissions from a Switched-Mode Power Supply (SMPS). The model for the emission is based on the assumption that each conductor (land) of the printed circuit board (PCB) of which the SMPS is composed can be considered as a Hertzian dipole. The currents in the lands are determined by means of approximate lumped circuits connected in different ways and using a circuit simulator like PSPICE.

Abstract
This paper presents an attempt to solve the problem of predicting radiated emissions from a Switched-Mode Power Supply (SMPS). The model for the emission is based on the assumption that each conductor (land) of the printed circuit board (PCB) of which the SMPS is composed can be considered as a Hertzian dipole. The currents in the lands are determined by means of approximate lumped circuits connected in different ways and using a circuit simulator like PSPICE.
