Abstract :
In this paper, a simplification method for reflective and rotational symmetry model, is proposed. Using spatial eigenmodes, the coefficient matrix of the final simultaneous equations for the time and storage capacity can be reduced. The proposed method can adapt to not only an integral-equation-method model but also finite element method model
