摘要
A method based on the parabolic wave equation is used to predict path loss in a two dimensional urban setting where buildings sprawl over irregular terrain. Propagation is assumed to take place in the vertical plane joining the transmitting and receiving antennas. A coordinate transformation is used to account for the irregular terrain features. The vertical walls of the buildings are assumed to be absorbing while the rooftops are taken to be Aat and reflective. Ground and rooftops are allowed to have different constitutive parameters. Both horizontal and vertical polarizations are considered. Comparison is shown with various other methodologies to demonstrate the ability and accuracy of the present method to accommodate various situations.
