5 GHz laterally-excited bulk-wave resonators (XBARs) based on thin platelets of lithium niobate
Victor Plessky,Soumya Yandrapalli,Patrick Turner,Luis Guillermo Villanueva,Julius Koskela,R. B. Hammond +5 more
TL;DR: In this paper, a 400-nm-thick platelet of crystalline ZY-LiNbO 3, narrow electrodes (500 nm) placed periodically with a pitch of a few microns can eXcite standing shear-wave bulk acoustic resonances (XBARs), by utilizing lateral electric fields oriented parallel to the crystalline Y-axis and parallel to plane of the platelet.
5 GHz Band n79 wideband microacoustic filter using thin lithium niobate membrane
Patrick Turner,Bryant Garcia,Ventsislav Yantchev,Gregory C. Dyer,Soumya Yandrapalli,Luis Guillermo Villanueva,R. B. Hammond,Victor Plessky +7 more
TL;DR: In this article, a 4.7 GHz bandpass ladder-type filter with 1 dB mid-band loss and 600 MHz bandwidth was proposed to address the 5G Band n79 requirements.

TL;DR: In this article, a free ZY-LiNbO3 400nm thick platelet, narrow electrodes (500nm wide) placed periodically with a pitch of few micrometers can eXcite standing Bulk Acoustic shear wave Resonances (XBARs), by means of lateral electric field parallel to crystalline Y- axis.

Ultra-Large-Coupling and Spurious-Free SH 0 Plate Acoustic Wave Resonators Based on Thin LiNbO 3
Jie Zou,Ventsislav Yantchev,Filip Iliev,Victor Plessky,Sohrab Samadian,R. B. Hammond,Patrick Turner +6 more
TL;DR: A novel perfect edge reflector is proposed with elimination of longitudinal spurious ripples in the design of the SH0 plate acoustic wave (PAW) resonators, applicable to the ultra-wideband filters and next-generation tunable filters.

Hierarchical Cascading Algorithm for 2-D FEM Simulation of Finite SAW Devices
TL;DR: A new 2-D algorithm is proposed that takes advantage of the periodic structure typical of SAW devices, implying the drastic reduction of memory consumption and simulation time for structures with a high degree of periodicity.
