Quartz Crystal Resonators             

Quartz  crystal resonators are widely used in communication, timing,  measurement, and other industries as one of the most important  traditional piezoelectric devices.  My research is concentrated on the  accurate analysis of quartz crystal resonators with Mindlin and Lee  plate theories.  We can provide accurate and reliable predictions of  frequency and effect of the electrodes, making it possible to study the  frequency stability under thermal fields and estimate the quality factor  in the product development process.  Our current research work is  focused on the electrical parameter estimation of quartz crystal  resonators.    

Our research results are closely related to industrial applications through joint programs and sponsored projects.    

Surface Acoustic Wave Resonators    

Surface  acoustic wave (SAW) resonators differ from quartz crystal resonators  mainly because the acoustic wave modes are the surface waves exist in  the vicinity of substrate surface.  SAW resonators are widely used in  communications and areas the higher frequency is required.    

We  are using the two-dimensional theory for the surface acoustic waves in  finite solids for our innovative analytical approaches to the product  design technology.
