摘要

The fundamental frequency dependence of the proximity effect of a quartz crystal resonator (QCR) has been experimentally observed. By an impedance analysis method, the response mechanism underlying this effect has been examined. It is found that the disturbance of the fringing electric field of QCR due to adjacent metal is the main reason. Moreover, this experiment demonstrates that the proximity effect of QCR is strongly associated with the fundamental resonance frequency. Also, the effect of the size of the adjacent copper disk on the proximity effect of QCR has also been studied. The accurate understanding and prediction of this effect, on one hand, can help us distinguish abnormal frequency fluctuation especially in the presence of the adjacent metal. On the other hand, this effect can also be used for sensing applications. (C) 2015 The Japan Society of Applied Physics
