An efficient iteration-free approach for scattering from multiple bodies of revolution

In this paper a numerically efficient strategy for solving the scattering problems from multiple Bodies of Revolution(BoR) is described. This approach is based on the method of moment(MoM) expand by BoR basis function. By using a current coefficient transform algorithm, the BoR halfglobal basis function is applied in multiple objects problems. As a result, the CPU time is reduced compared with RWG method. MLFMA is also be applied to accelerate the matrix-vector product in the method proposed here. The accuracy and efficiency of the method is demonstrated in some scattering problems.
