Identification of dominant propagation mechanisms around corners in a single-floor office building

Radio wave propagation mechanisms around concrete corners in a single-floor office building have been investigated numerically using the FDTD. Penetration through and diffraction around the corner can be neglected as reflection is seen to dominate. Simulation results show that a precise knowledge of wall permittivity may not be required, as the dominant reflected component from both concrete and drywall models are of comparable size to those obtained using a PEC wall model. These results also suggest that drywall and concrete wall could be modelled as PEC with a prediction error about 5 dB and 3 dB, respectively.
