General, linear boundary conditions in MD wave digital simulations

Recently, publications by Fettweis, et al. (1991) have divulged a new technique for simulating systems of partial differential equations (PDEs) in discrete space-time. This technique, based upon multi-dimensional wave digital structures, holds much promise for the stable simulation of systems of PDEs that model critical physical phenomena. To date, however, little has been published concerning handling other than the simplest types of boundary conditions for such systems. Here, in the one-dimensional transmission line case, is presented a straight-forward method for accommodating general, lumped, linear boundary terminations that appears to be extendable to higher dimensions
