Extension of the hybrid FEBI-MLFMM-UTD method to finite curved objects

In this paper the hybrid Finite Element Boundary Integral (FEBI), the Multilevel Fast Multipole Method (MLFMM) and the Uniform Theory of Diffraction (UTD) method are extended to treat large curved objects by UTD. This work has been done at the post processing stage of the hybrid method. The various examples considered to evaluate this extension are introduced, the obtained results and the further modifications required are presented.
