Abstract :
A new multipoint moment matching based reduced order modeling approach is proposed to obtain a broadband macro model of complex systems. With the new technique, the least square matrix obtained is better conditioned than that of the AWE-like approach and a high order rational approximation can be achieved to yield a highly accurate broadband model.
