Figure 7

Behavior of resonance amplitude versus salinity at lowest resonance frequency. Crosses denote results for capacitive model while solid lines-for galvanic model of the coupled open ended coaxial waveguide resonator. Results are presented for liquid thickness \(h=4\mbox{ mm}\), \(R_{\mathrm{WLR}} = 1\), \(R_{\mathrm{DGR}} = 10^{-5}\). The resonance amplitude is shown at the left figure and change in the resonance amplitude is presented at the right figure.
