An adaptive homogenisation process applied to the urban environment

This paper presents a dynamic way of dealing with homogenisation in the urban environment. The first part is dedicated to finding which zone on a wall scatters most of the energy when the observation point is close to the wall. In the second part, the wall is homogenised according to the zone defined in the first part, and we compare the results with the heterogeneous case. The homogenised far field is accurate and homogenisation is a valid way of determining fields within a given uncertainty
