Excitation of lateral waves and the scattered radiation fields by rough surfaces of arbitrary slope


  • Ezekiel Bahar


The coupling between the lateral waves and the radiation field by rough surfaces is derived using a full-wave approach. Both horizontally and vertically polarized waves are considered, and the solutions are shown to satisfy the reciprocity and duality relationships in electromagnetic theory. The slope of the rough surface is not restricted, shadowing effects are considered, and the solutions are also applied to random and periodic rough surfaces. Using stationary phase techniques, closed-form solutions are also derived for high frequencies.
