Abstract
The microwave propagation characteristics of the superconducting coplanar waveguide structure that incorporated a ferroelectric thin film were theoretically studied by utilizing the spectral domain method. Tunability of the transmission characteristics was introduced by the inclusion of the ferroelectric thin film, whose permittivity can be tuned by an external electric field. The dependence of tunability on the thickness of the layers, as well as the operating temperature, was explored within the \(K_u\) band of the spectrum. The effect of spurious magnetic fields on the superconducting strip, and thereby on the propagation characteristics of the waveguide, was also investigated. The tunable propagation characteristics of microwave waveguides obtained suggest the potential for application in satellite communication, in radar systems, and in circuit quantum electrodynamics.
