METHOD FOR EXTENSION OF DIELECTRIC CONSTANT AND LOSS MEASUREMENTS OF LIQUIDS TO 100 MHZ WITH A FIXED-GEOMETRY SAMPLE HOLDER

Abstract

A method for measuring the dielectric properties of liquid specimens on a Q-meter at frequencies up to 100 MHz was developed by (1) assuming an equivalent circuit for a cylindrically shaped liquid-sample holder, (2) determining relevant circuit parameters by experiment, and (3) deriving the necessary equations taking full account of the effects of sample-holder inductance. Measurements made on two liquid samples are detailed and show that good accuracy is obtained when the standard liquid employed is a lossless dielectric with dielectric constant (K) near the K of the sample under test.
