Rapid Measurement of Dielectric Constant and Loss Tangent

IEEE Transactions on Microwave Theory and Techniques, 1956
The problem of evaluating dielectric constant and loss tangent by the short-circuited-waveguide technique has been encountered continually in recent years in the study of artificial dielectric media and radome materials. In general, practical measurements have involved materials with low loss and dielectric constants less than 10. The analytical method

The quadrant electrometer for the measurement of dielectric loss

Journal of the A.I.E.E., 1924
Walker, Skinner, Addenbrooke, Rayner, Orlich, Schultze, Thielers and others* have given a great amount of useful information on electrometers for the measurement of dielectric loss. We have found instruments made somewhat after the design of Skinner and Rayner, so rugged, and so useful as laboratory instruments, even when the instrument is subjected to

Calorimetric measurement of dielectric losses in solids

Electrical Engineering, 1936
A new transient calorimetric method for measurement of dielectric losses in solids at 10,000 volts and 1,000 kilocycles, is described in this paper and experimental data obtained by this method are presented. A steady-state method also is described and a direct comparison between the results obtained by the 2 methods is given.

Measurement of Dielectric Loss and Wall Loss in a Dielectric-Filled Waveguide

IEEE Transactions on Instrumentation and Measurement, 1974
A waveguide bridge capable of measuring dielectric loss down to 5 ?rad at frequencies of 10-35 GHz is described. A major uncertainty was the value of the wall loss. This has been resolved by measuring the wall loss of the specimen arm both with air and dielectric filling.

Microwave Measurements of the Loss in Low Loss Dielectrics

Review of Scientific Instruments, 1970
A technique has been developed which offers a significant improvement in the measurement of the loss in low loss materials having dielectric constants ≥4. The device consists of a cutoff section of circular waveguide concentrically loaded with a rod of the dielectric to be measured.

Dielectric Loss and Dielectric Constant Measurements in Supercooled Liquids

Proceedings of the Physical Society. Section B, 1950
In order to provide further evidence in support of the structural change which takes place in a liquid when it is supercooled, measurements of dielectric loss at high frequencies and of dielectric constant have been made on various polar liquids. The evidence from the dielectric loss measurements is inconclusive but for the four liquids tested a ...
