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

Low-loss dielectrics are important technologically as insulators but there is little understanding of the physical causes of this property and even their spectral response is not well documented—this study has revealed a number of different types of behaviour which do not appear to have been recognised previously. Most low-loss materials show a “flat”,

Measurement of Dielectric Loss and Wall Loss in a Dielectric-Filled Waveguide
IEEE Transactions on Instrumentation and Measurement, 1974A 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.

Loss Mechanisms in Dielectric-Loaded Resonators
IEEE Transactions on Microwave Theory and Techniques, 1985Analysis is presented of resonators consisting of a section of a dielectric-loaded waveguide shorted at both ends. The analysis includes resonant frequency calculations, mode charts, and unloaded Q computations. Numerical results are presented for the unloaded Q's of various modes, as a function of the resonator parameters.

Limiting losses in dielectrics
IEEE Transactions on Dielectrics and Electrical Insulation, 2001Examination of a wide range of experimental data relating to 'low-loss' dielectric materials reveals the little acknowledged fact that their loss at high frequencies (kHz to GHz) and low temperatures (typically 100 to 200 K) is weakly or very weakly dependent on frequency, what we call 'flat loss', and is likewise weakly dependent on temperature ...

Low Loss Dielectric Waveguides
IEEE Transactions on Microwave Theory and Techniques, 1954The history of dielectric waveguides begins back in 1910 with the publication of a theoretical paper by Hondros and Debye, who gave a mathematical treatment of transverse magnetic mode propagation in lossless dielectric guide. In the 1930's Southworth began experimental work on these modes while Carson, Mead, and Schelkunoff developed a general theory ...

Dielectric nanocomposite with high dielectric permittivity and low dielectric loss
2015 IEEE Electrical Insulation Conference (EIC), 2015Dielectric flexible nanocomposites featuring ferroelectric barium titanate nanoparticles embedded in poly(vinylidene fluoride) (PVDF) matrix were fabricated by a miscible-immiscible coagulation method followed by hot pressing. The SEM images showed good distribution of nanoparticles with very little particle agglomeration.
