Description: The problem of radiowave propagation over irregular terrain is solved by using the wide angle parabolic equation method. The terrain is characterized by its height profile and its ground constants (here conductivity alpha goes to infinity). We consider horizontal polarization and treat the round as perfectly conducting (PEC) to simplify the formulation. This thesis uses a piece-wise conformal transformation to flatten the irregular terrain. The equations are solved by the split-step Fourier algorithm. A Hanning window is used both in spatial and in wavenumber domains to contain the computational domain. Effect of some numerical parameters such as the horizontal step size height of the computational domain on the accuracy of the solution is investigated. The numerical results are compared with available results for some typical propagation problems
