摘要：
The symmetry present in body of revolution (BOR) electromagnetic scattering problems permits an efficient numerical solution using a 2D technique. However, in many practical problems, the rotational symmetry is broken by the presence of small appendages. Thus, a 3D computational method is required to rigorously compute the electromagnetic scattering. Because of the increased computational complexity of a 3D method, a hybrid method is developed which allows the scattering from small appendages to be approximately combined with the scattering from a large BOR in a similar manner to other hybrid techniques.
