Accurate L-band dielectric constant measurements of seawater

A temperature controlled resonant cavity is used to measure the complex dielectric constant of seawater at 30 psu over the temperature range from 10°C to 35°C at 1.413 GHz. The measurements are conducted multiple times to obtain the mean and the standard deviation at each point. This paper describes the experimental procedure and presents recent dielectric constant results. These results are compared with the values obtained using the Klein-Swift model function.
