Comments on "CAD models for asymmetrical, elliptical, cylindrical, and elliptical cone coplanar strip lines"

Abstract

For original paper see Z.Du, K.Gong, J.S.Fu, Z.Feng and B.Gao, ibid., vol.48, no.2, pp.312-6 (Feb 2000). In the original paper, Du et al. present analytical closed-form expressions for the quasi-TEM parameters for asymmetrical coplanar strip lines with a finite boundary substrate by using the conformal mapping technique. In this paper Gorur and Karpuz comment on their results. A reply to their comments by the original authors is included.
