Comments on "Analysis of superconducting microwave structures: application to microstrip lines" [with reply]

For the original article see ibid., vol.40, no.3, p.499-508 (1992). The commenters present experimental and theoretical evidence that purports to show that in the above-titled paper by S.M. El-Ghazaly et al. and an earlier paper by the same authors, the distribution of longitudinal current component J in the transverse plane is related to the surface charge density rho /sub S/ and the distribution of J/sub z/ in the transverse plane varies with the dielectric constant of the substrate. El-Ghazaly replies that the commenters failed to understand some salient features of his papers. Also, he argues that they overestimate the application of Wheeler´s approximation, namely the inductance per unit length is independent of the dielectric constant in transmission lines, and he provides clarification.<>
