Stochastic Analysis of Scattered Field by Building Facades Using Polynomial Chaos
Résumé
This paper presents a statistical assessment of
scattered field from a building facade having random physical
and geometrical parameters. A simple inhomogeneous model is
considered for the building and the calculation method is based
on Green’s functions. The basis of polynomial chaos expansion
method is explained and applied to estimate the scattered electric
field from a building facade having 8 random parameters, in
specular and non-specular scenarios. Uncertainty analysis and
total output distribution are discussed in different diffraction
zones of the building.
