SC-cut resonator with reduction of B-mode electrical response

Excitation, by the use of two pairs of cross-connected half electrodes, of SC-cut resonator operating on first anharmonic modes is considered. In order to obtain resonators having the best electrical response of the C-mode, it is shown that two cases can be encountered, depending on the shapes and orientation of modes, i.e. on overtone number. The computation of electrical parameters is based on Lewis formula and use of analytical expressions for the vibration and the electric field
