Abstract
A method of measuring the dielectric properties of medium and high loss liquids at microwave frequencies is described. In this method the liquid sample is placed in an open circuit-terminated section of wave-guide and standing wave-ratios are measured at intervals as the length of the dielectric liquid column in the wave guide is changed. The method of measuring the wave-length of the radiation in the liquid-filled wave guide is indicated. A simple procedure for calculating the dielectric properties from these measurements is presented. Some dielectric properties of liquids measured with this method at 3-cm wave-length are given.
