Abstract	In this paper we use a simplified method which was proposed to solve the problem of scattering by a lamppost. It is shown that this method is usable and accurate enough to compute the scattered near fields by the other single metallic objects in a typical microcell scenario. In fact, we model the transmitter antenna radiation with two ray incidence model and compute the current elements values using Multi-level Fast Multi-pole Method. To compute the scattered near fields, current elements radiation above the real ground is considered using discrete complex image method with generalized pencil-of-function expansion. Furthermore, we consider a more realistic scenario in which multiple metallic objects are present. In this scenario we examine the accuracy of the single scattering assumption and confirm that we can superimpose the scattered fields by single objects in order to find the total field with an acceptable error.
