Finite Difference Interpretation

It should be clear that a MDWD network corresponding to a particular MDKC (and thus to a given set of PDEs) is no more than a particular type of finite difference method, and can be analyzed as such. We will do so here for the case of the (1+1)D transmission line, in order to compare the schemes that arise from the WD approach to the simple centered difference schemes which will be introduced in the next chapter in the waveguide context, and which can also be put into a scattering form.
