●　主題：　RF Micro Devices Based on Lithium Niobate Thin Film
●　摘要：　This talk briefly reviewed the latest progress and development work of lithium niobate (LiNbO3/LN) thin film devices. In recent years, subwavelength-thick LN thin film technologies open up new horizons for various wave modes with high electromechanical coupling and low acoustic loss. To elaborate on the potential and performance of LN thin film devices for RF applications, this talk will first discuss the acoustic modes at a device designer’s disposal and their characteristics. Next, several demonstrations for overcoming the challenges in translating LN’s great material properties to working devices will be discussed.
