The main subject of this thesis is to study the characteristic of TSM and to set up an analyzing model of TSM resonator for design and applications.
At present, TLM, BVD or EBVD equivalent circuit have been applied on TSM resonator, especially for QCM. We utilize a kind of new analytic way-TWSF in this article. This method is need to find out the correlation between each parameter, for more accurate and convenient. Utilizing this analytic way standing shear wave phase angle shift can be calculated. The shift of resonant frequency and admittance response can also be calculated by the phase shift and loading impedance. In addition, this model is used to derive the formulas of frequency shift and admittance while the loading are the Maxwellian fluid or the viscoelastic fluid.
