Propagation features of a class of beams radiated from pseudo-Schell model vectorial sources

Pseudo Schell-model sources were introduced and studied in the scalar domain as those partially coherent sources that present a degree of coherence depending on the difference between the radial coordinates of the two considered points. In this work we study the propagation features of a class of be...
