Far-field Cyclostationary Characterization of Emissions from DUT Based on the Jefimenko’s Equations

In this paper the analytical time-domain propagator for stochastic electromagnetic field is proposed. The two-dimensional auto-correlation function and cyclic auto-correlation function can be efficiently used for the far-field characterization of the printed circuit board (PCB) stochastic radiated emission in the time-domain. The calculated cyclic characteristics using the convolution transformation and the far-field antenna measurements are compared. The validation of the obtained characteristics is demonstrated using normalized impulse antenna response.
