Comments on "Modeling of cylindrical objects by circular dielectric and conducting cylinders" [with reply]

In the above-titled paper (see ibid, vol. 40, p.96-9, 1992) A. Z. Elsherbeni and A. A. Kishk introduced a general method and semianalytical solution for the modeling of composite two-dimensional scatterers. The commenters point out that unnecessarily large numbers of terms were used for thin conducting wires with TM excitation. The original authors point out that the expression for the number of terms they used is needed for the more general case. The commenters also suggest that the wire grid model for the scattering by a conducting cylinder yields, in general, a matrix equation of smaller order relative to the matrix equation generated by the circular cylinder model. The authors refute this suggestion and clarify a number of other points as well.<>
