Time-Domain Analysis of Stochastic Electromagnetic Fields based on Jefimenko's Equation

A method for time-domain modelling of the noisy electromagnetic fields radiated from complex circuit boards is investigated. The time-domain analysis of stochastic EM fields is based on Jefimenko's equations yielding the electric field and the magnetic flux density caused by a charge density and current density. We introduce a four-dimensional source vector by summarizing the source current density and the source charge density into a four-dimensional source vector.
