The development of ultrasonic-guided wave sensors is of great significance for structural health monitoring (SHM). In this work, a shear horizontal (SH) ultrasonic guided wave sensor based on the Ca3TaGa3Si2O14 (CTGS) piezoelectric single crystal is demonstrated. The findings reveal that the CTGS-based ultrasonic guided wave sensor is proficient in transmitting and receiving pure fundamental SH wave (SH0 wave) along two orthogonal main directions (0° and 90°) over a wide frequency range (100–350 kHz), exhibiting strong response to the SH0 wave. Under the driving voltage of 100 V, the peak-...

Sample Preparation and Deprocessing Silicon Photonic Devices The symposium has consistently provided attendees with the latest analysis techniques necessary to obtain accurate and timely information on device-related issues. The collected proceedings papers now available in the ASM Digital Library serve as a comprehensive reference of the state-of-the-art research, development, tools, and techniques as presented at ISTFA conferences over the most recent quarter decade. "The launch of ISTFA Proceedings enables convenient access to this valuable content to the EDFAS membership and the broader...
