Abstract

The increasing importance of a knowledge of dielectric constants of substances is shown by the large number of measurements that have appeared in recent literature- Several methods have been used in making these measurements, but probably the most precise ate the methods based on the heterodyne beat principle. This apparatus is designed to measure substances that are non-conducting. The condition of constant capacitance in the measuring circuit is the principle of the apparatus and is detected by the beat note between a fixed crystal radio frequency oscillator and oscillations generated by a variable oscillator. Otto and Wenzke (6) have used this principle with extremely precision results. ~e condition of maintaining constant capacitance in the measuring circuit is the most commonly used method in such measurements.
