Title: "Lithium Niobate on Insulator Wideband Surface Acoustic Wave Devices"
Date: Wednesday, 01st July 2026 - Time: 4 PM

Venue: CeNSE Seminar Hall

Abstract:

Next-generation wireless communication systems require large-volume, high-speed data delivery, 
driving the need for wideband RF signal-processing functions. This has accelerated the development 
of wideband micro acoustic devices using emerging piezoelectric materials. Among them, surface 
acoustic wave (SAW) devices based on thin-film lithium niobate on insulator (LNOI) are highly 
promising, offering strong electromechanical coupling, frequency scalability, mechanical 
robustness, excellent power handling, and relatively simple fabrication. This talk presents 
an overview of recent advancements in high-performance and wideband SAW resonators, filters, 
and acoustic delay lines (ADLs) based on LNOI technology, and further explores their potential 
applications in the C-band and X-band.
