摘要：

In previous papers an equivalence between the TLM and FD-TD methods has been established by altering the definitions of field components and operation of the TLM algorithm such that the appropriate finite-difference expressions are satisfied. In this paper the equivalence of propagation characteristics for the TLM and FD-TD methods in two dimensions is discussed. Propagation analysis of a TLM shunt node complete with permittivity and loss stubs, and dispersion analysis of the two-dimensional FD-TD method in an arbitrary medium are performed and yield dispersion relations. The relations are identical when the FD-TD method is operated at the upper limit of its stability range.
