6mm LS Mode

The length shear mode occurs in specimens with the following geometry;

The arrow represents the sample poling direction. The limits in dimension should ensure that the resonance will be free of coupling with other resonance modes.

The resonance observed in the sample impedance is described by the following equation;

By fitting this equation to the observed resonance, the following material properties can be determined;

k₁₅, s^E₅₅, d₁₅, e^T₁₁
