A novel Finite-Element Method - Parabolic-Equation (FEMPE) based MATLAB tool is developed. This calculates the electromagnetic field strength and path loss for one-way, forward propagation over multi-mixed irregular terrain paths through an inhomogeneous atmosphere, recommended by the ITU. The well-known smooth-Earth Millington curve-fitting model, based on analytic ray and mode approaches, is also included.
