Summary :

In this paper we will propose a deterministic approach to model the radio wave propagation channels in large empty buildings. This technique applies the modified SBR method to find equivalent sources (images) in each launched triangular ray tube, and sums the receiving amplitude contributed by all images coherently. In addition, vector effective antenna height (VEH) is introduced to consider the polarization coupling effect resulting from the multiple reflection inside the buildings. We verify this approach by comparing the numerical results in three canonical examples where closed-form solutions exist. The good agreement indicates that our method can provide a good approximation of high frequency radio propagation inside buildings where multiple reflection is dominant. Work reported in this paper has shown that propagation loss in large empty buildings can vary considerably according to the geometrical configurations of buildings and polarizations. This SBR/image method can be enhanced by including the wall penetration and wedge diffraction effects so that more complicated indoor environments with furniture will be handled. Additional considerations, such as buildings crowded with pedestrians are left for future studies.
