Path loss predictions in urban areas sprawling over irregular terrain

A method based on parabolic wave equations is used to predict path loss in a two dimensional urban setting where buildings sprawl over irregular terrain. 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 flat and reflective. Ground and rooftops are allowed to have different constitutive parameters. Comparison is shown with various other methodologies to demonstrate the ability and accuracy of the present method to accommodate various situations
