  Relying on Feynman-Kac path-integral methodology, we present a new
statistical perspective on wave single-scattering by complex three-dimensional
objects. The approach is implemented on three models -- Schiff approximation,
Born approximation and rigorous Born series -- and usual interpretative
difficulties such as the analysis of moments over scatterer distributions
(size, orientation, shape...) are addressed. In terms of computational
contribution, we show that commonly recognized features of Monte Carlo method
with respect to geometric complexity can now be available when solving
electromagnetic scattering.
