Analysis of Dispersion in Ferrite-superconductor Layered Structures

摘要

This paper studies electromagnetic wave propagation in hybrid structures consisting of ferrite and superconducting films. Dispersion relations for transverse electric mode of propagation are derived. Numerical results are presented for two specific structures viz. a ferrite/superconductor structure and a ferrite/superconductor/ferrite structure and dependence of propagation on various structural parameters and frequency are determined. The non-reciprocal nature of propagation is also established.
