Abstract
Some new results are established regarding a recently developed coherent-mode representation of steady-state sources and fields of any state of coherence. It is shown that when a planar source is spatially band limited in the sense that its cross-spectral density function contains only spatial frequencies smaller than the corresponding wave number, the mode representation has some very simple and useful properties. Some potential applications of the results are mentioned.
