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.<
