Design and Analysis of Lithium–Niobate-Based Laterally Excited Bulk Acoustic Wave Resonator with Pentagon Spiral Electrodes
TL;DR: In this article , the A1 mode resonators with pentagon spiral electrodes utilizing Z-cut lithium niobate (LiNbO3) thin film are designed and fabricated.
High-Q A0 Mode Plate Wave Resonator on X-cut LiNbO3 Films with Dummy Electrode Arrays
TL;DR: In this paper , a high-Q A0 mode plate wave resonator with dummy electrode arrays on a suspended X-cut LiNbO3 film is presented, where more energy is concentrated in the central region and lead resistance is reduced using dummy electrodes arrays, resulting in a significant increase in the Q factor.
