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.

Dielectric losses in ferroelectrics of displacive type as compared to the losses in ordinary dielectrics

Ferroelectrics, 1985
The theory of intrinsic (phonon) dielectric losses in ferroelectrics of displacive type is reviewed and compared with the theory of losses in ordinary dielectrics. The authors in 7-12 have calculated the temperature and frequency dependence of losses for a wide range of variation of the parameters.

Dielectric loss in boron

Journal of the Less Common Metals, 1979
Abstract The temperature dependence of the dielectric loss (tgδ) in β-B was studied at temperatures ranging from −196 to 350 °C and at frequencies of 1–104 Hz. The curve of the temperature dependence of dielectric loss in an electric field with a frequency of 50 Hz showed two relaxation maxima at −65 and −45 °C characterized by activation energies of

The Dielectric Losses in Impregnated Paper

Transactions of the American Institute of Electrical Engineers, 1933
Accurate measurements have been made of the electrical and other physical properties of 10 insulating oils, of a single grade of wood pulp paper, and of the paper when impregnated with each of the oils. Short time charge and discharge curves under continuous potential have thrown further light on the anomalous conduction as found in oils, and permit ...
