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...
A weak coupling technique for an electromagnetic and a structural dynamic model formulated by the finite element method (FEM) is presented. The algorithm is able to estimate higher force harmonics with high accuracy and is hence suitable for acoustic simulations of electrical machines. High computational efforts using conventional algorithms are reduced significantly and accuracy is even enhanced...
