Abstract :
An analytical approach is presented to describe acoustic thickness shear mode resonators in the full frequency range, including all overtones. The absolute value of loadings with complex properties (e. g. complex viscosity or shear modulus) can be determined by curve fitting. Loadings with complex behaviour like polymer layers have been studied and can be described. The appearance of layer resonances in thick metal layers have been predicted and proven at even numbered overtones which has generally been considered to be not possible.
