Optimal design work for high-frequency quartz resonators

My research focused on improving the performance of AT-cut high-frequency quartz resonators, which have been used in a wide range of applications including frequency generators, frequency control of telecommunication systems. New research findings about optimal design of AT-cut high-frequency quartz resonators fabricated by newly developed etching process were presented through improving energy trapping and reducing spurious vibration couplings. The simulation and experimental verification were carried out, and the effectiveness of the optimal design was validated. The main optimal design works include five cases.
