THICKNESS-SHEAR VIBRATION OF A RECTANGULAR QUARTZ PLATE WITH PARTIAL ELECTRODES被引量：1: 2013年; We study free vibration of a thickness-shear mode crystal resonator of AT-cut quartz. The resonator is a rectangular plate partially and symmetrically electroded at the center with rectangular electrodes. A single-mode, three-dimensional equation governing the thickness-shear displacement is used. A Fourier series solution is obtained. Numerical results calculated from the series show that there exist trapped thickness-shear modes whose vibration is mainly under the electrodes and decays rapidly outside the electrodes. The effects of the electrode size and thickness on the trapped modes are examined.; Huijing HeJiashi YangJohn A. KosinskiJi Wang; 关键词：VIBRATION PLATE
