Abstract
Quadratic structure functions are sometimes used to describe the phase of partially coherent waves. The physical significance of such structure functions, that they describe a tilted but unwarped phase, limits their applicability to propagation calculations. Calculation of processes in which the principal effects are due to phase-front tilting may be simplified by recognizing that fact.Keywords
