A procedure for modeling the general electromagnetic Schell-model vortex light source is proposed. Based on this method, we introduce a new class of stochastic electromagnetic vortex light sources with multi-Gaussian Schell-model coherence function. The far-field statistical properties of the beams generated by such sources are studied in detail by numerical examples. Our results can be used to determine the mode structure of a new class of stochastic electromagnetic vortex light sources and of the radiation fields generated by them.
