For the original article see ibid., vol.28, p.2353-4 (1992). The commenters state that they have developed several models for simulating wire structures and are very familiar with the difficulties involved in the resolution of the nonlinear equations system required for obtaining the scattering matrix. It is for this reason that they very much appreciate the procedure proposed by Naylor and Ait-Sadi in the above mentioned. In using this procedure, however, the commenters have found a minor error: two equations which associate incident and reflected voltage pulses at the particular pair of lines under consideration, are only valid when both lines are of the same characteristic impedance. This is demonstrated in an example. In reply the authors concede that there was an error but believe that the operation of the method has been misunderstood. They then discuss certain points in an effort to clarify the situation.
