The Electromagnetic Wave Propagation on the Interface between Low and High Loss Dielectrics
Figure 3
The dependence of the attenuation coefficient (a) and the normalized phase velocity (b) to the light velocity in the quartz rod for the wave in cylinder round rod. Complex permittivity of the outer medium is (curve 1) and (curve 2). The operating frequency is 31.82 GHz. The stars denote experimental data points from [14] (the outer medium was taken as water-ethanol solutions at 23°C from 10% to 70% ethanol in water [22, 23]).
