Expanded GMC for transient analysis of transmission line networks

This paper describes the expanded generalized method of characteristics (GMC) in order to handle large linear interconnect networks. The conventional GMC is applied to model each of transmission lines. Therefore, this method is not suitable for dealing with large linear networks containing many transmission lines. Here, we propose the expanded GMC method to overcome this problem. This method computes a characteristic impedance and a new propagation function of the large linear networks containing many transmission lines. Furthermore, the wave propagation delay is removed from the new wave propagation function using a delay evaluation technique. Finally, it is shown that the present method enables the efficient and accurate simulation of the transmission line networks.
