Abstract :
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/ m applied to the slotline electrodes, and has several advantages: (i) a low cutoff frequency of a few megahertz compared with several gigahertz for open-dielectric waveguides, and (ii) a high degree of hybridisation of magnetostatic surface spin waves and electromagnetic modes that results in excellent tunability.
