Domain decomposition method for scattering from multiple bodies of revolution

In this paper, a domain decomposition method is developed for scattering from multiple conducting bodies of revolution (BoR). The BoR basis functions are utilized to solve the single BoR problem and multilevel fast multipole algorithm (MLFMA) is used to take into account the interaction between multiple BoRs. Because the MLFMA cannot be applied for entire domain basis functions directly, a basis function mapping technique (BFMT) developed by us is used to transform the BoR basis functions into RWG basis functions to overcome this difficulty. Numerical results prove the validity and efficiency of the present method.
