Abstract : 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.
Keywords : Terms—Scattering urban environment architectural details uncertainty analysis polynomial chaos
