Description: Formulation is given for efficient parabolic equation solution of radiowave propagation in      inhomogeneous atmosphere and over irregular terrain. Both standard and wide angle      parabolic equation derivations are presented. Impedance boundary conditions are used to      characterize the ground. A tropospheric boundary condition based on the exact solution of      Schroedinger equation in a quarter plane is derived. To permit efficient modeling of the      irregular boundary, the parabolic equation together with the boundary conditions is      transformed into a numerically generated curvilinear coordinate system. Finally, formulation is      presented for a finite difference solution using Crank- Nicolson implicit scheme. Radiowave      propagation, Parabolic equation, Finite differences.
