Abstract

In this paper an efficient method is proposed for computing electromagnetic wave propagation in urban areas. The paper extends the Block Forward Backward Method (BFBM), combining the BFBM with the Fast Fourier Transform based method to accelerate the calculation of the currents on the blocks and remove the need for direct local matrix inversion. The simulation results show that the path-loss generated by the forward BFBM-FFT has a better agreement with the measurement data than that generated by the slope diffraction method (SDP) which is a vertical plane model and used as the reference method in this paper.
