Dual tunable thin-film ferrite-ferroelectric slotline resonator

A novel microwave resonator of yttrium iron garnet and ferroelectric barium strontium titanate films in a slotline structure is proposed. The resonator is electric field tunable, by 75 MHz for E = 5 V/μm applied to the slotline electrodes, and has several advantages: a low cutoff frequency of a few...

Zusammenfassung:A novel microwave resonator of yttrium iron garnet and ferroelectric barium strontium titanate films in a slotline structure is proposed. The resonator is electric field tunable, by 75 MHz for E = 5 V/μm applied to the slotline electrodes, and has several advantages: a low cutoff frequency of a few megahertz compared, with several gigahertz for open-dielectric waveguides, and a high degree of hybridisation of magnetostatic surface spin waves and electromagnetic modes that results in excellent tunability.
