Abstract :
A model for electromagnetic scattering from natural rough surfaces described by means of fractional Brownian motion model is developed. The fractal surface model is employed to obtain the Kirchhoff solution of the Stratton-Chu scattering integral. An analytical viable formulation is achieved and compared to available classical solutions. Comparison with experimental data is also provided. Results show advantages of proposed solution from both theoretical and experimental viewpoint
