We evaluate the modes for generalized Schell-model planar source whose complex degree of coherence (CDC) is a function of the n-th power difference of two position coordinates instead of their direct distance between two source points. We discuss through two examples how new classes of CDCs can be devised and how they affect the radiation fields. It is demonstrated that the light beams generated by these families of sources carry interesting propagation characteristics, such as the lateral self-shifting and the self-focusing effect with controllable focal length determined by the non-trivial phase, power n and other source parameters.
