Abstract

This paper deals with the microwave propagation characteristics of a superconducting slotline waveguide structure supported by a ferroelectric thin film. The variation of the propagation constant and attenuation constant with biasing electric field was theoretically studied using the spectral domain method. The dependence of the propagation characteristics on the operating frequency and temperature was investigated. The influence of geometrical parameters like thickness of the ferroelectric thin film, width of the slot, and thickness of superconducting strip constituting slot was analyzed at different biasing electric fields.
