Building facade homogenization in multiple reflection mechanism

A homogenization technique is applied to calculate the complex reflected electric field in a single reflection case. Using the validity domain of this case, a double reflection scenario with appropriate distances between buildings is studied. The precision obtained by the homogenization technique is compared to the case where the heterogeneities are completely neglected. For the regions within the validity domain of homogenization, an accelerating method based on the RCS (Radar Cross Section) techniques is proposed.
