The proliferation of communication system used in and around man-made structures has resulted in growing need to determine the scattering properties of various commonly used building materials at radio frequencies typically used in business and residential environments. This paper describes the calculation of scattered wave by reinforced concrete walls. For these walls is modeled with a grid of straight wire. We used the Method of Moments (MOM) to find the wire currents. The complex images (CI) method is also used to rapidly evaluate spatial-domain Green’s functions for the wall. The angular dependence of scattered fields is shown.
