We present an approach to problems of diffraction that has its roots in a number of well‐established theories such as the geometric theory of diffraction, the methods of Feynman’s path integrals and Wiener’s functional integrals, and the theory of stochastic processes. We start our analysis of the Helmholtz equation by closely following the scheme of the ray method, but instead of approximating the resulting second‐order auxiliary equation by a first‐order transport equation, we study the…

A probabilistic approach to wave propagation and scattering
The probabilistic approach to wave propagation starts in a way that is similar to ray theory, from the representation of the wave field as a product of the amplitude and of the exponent of the

TLDR
The results showed that the uncorrelated scattering assumption remains valid for the discrete finite spectra when the scattering objects are distributed randomly and that the correlation among wave components from different angles increases only when the randomness of the scatterer distribution is reduced.
