In this paper, the surface diffracted Uniform theory of Diffraction (UTD) fields which are excited at the grazing incidence on a curved object are considered in the framework of the hybrid Finite Element Boundary Integral (FEBI), the Multilevel Fast Multipole Method (MLFMM) and the Uniform Theory of Diffraction (UTD) method. Some of the examples that were considered in this work are described and the obtained results are discussed.
