Abstract :
The fast multipole method (FMM) and the impedance boundary condition (IBC) are used to attain an efficient computation of RCS of a 3-D coating conductor. FMM expedites greatly the matrix-vector multiplication in iterative process. Meanwhile a sparse technique combined with precondition conjugate gradient method is used to carry out the computation of two sparse matrices A~, B~. The present method is very efficient for solution of scattering from the impedance coating conductor with arbitrary shape and large electrical sizes.
