Popis:	A new electrodeless method is developed for RF dielectric constant and loss measurements. In the new method a sample coil is used instead of a conventional parallel plate capacitor sample cell. The changes in coil impedance due to the sample placed inside the coil are measured by a Q-meter. This method is not as accurate as previous methods but is convenient and mostly applicable to studies of polar liquids and solutions. Test measurements are made with various measuring conditions. An example application to glycerol-water mixtures verifies its applicability.
