Dispersion and Sensitivity Analysis of Quasi-Scholte Wave Liquid Sensing by Analytical Methods
Figure 2
Dispersion curves for a 1 mm aluminum waveguide embedded in water: calculated phase velocity (solid), calculated group velocity (dashed), and experimentally verified phase velocity data points (square) digitized from Figure 1 of [3]. Material properties: cL,al: 6320 m/s, cS,al: 3130 m/s, cL,w: 1500 m/s, ρal: 2700 kg/m3, and ρw: 1000 kg/m3.
