Evolution of transverse correlation in stochastic electromagnetic fields
In this work the evolution of the transverse correlation with increasing distance is investigated analytically and numerically. To characterize a stochastic EM field by measurements we have to sense the electromagnetic field in pairs of sampling points and to compute the correlations of all pairs. In the far-field, the field cross correlation functions depend only on the coordinate differences. This yields a considerable reduction of the measurement effort.
