<正> For the normal 2-D TLM model it's not possible to simulate the inhomogeneous materials corresponding to the tangential field components, at whieh ease a much more complicated 3-D model has to be used. Thus an improred 2-D TLM shunt node is devoloped so that all the 2-D inhomogeneous structures can be simulated with it.The despersion of tke wave Telocity of the node ia analyzed, then a mierostrip waveguide is modelled and the good aggreements of the results show the rightness and the effectiveness of it.
