Abstract
Blockage and backscattering by objects are relevant phenomena in millimeter-wave propagation. Conventionally, these phenomena are treated by means of separate models and, in turn, included in the total channel response. In this letter, we propose a combined model for calculating both blocked and backscattered fields from planar smooth electrically-large rectangular surfaces. The contributions of this letter are twofold: first, a single formulation for calculating both blocked and backscattered fields; and second, backscattering models are proposed for calculating blockage as well. Furthermore, the proposed model can be implemented using several models and, finally, is validated with electromagnetic simulations and measurements. Due to its computational efficiency, the model can be suitable for system- and link-level simulations of wireless systems, particularly when Monte Carlo simulations are applied.
