Dielectric losses in As2Se3 glass

Solid State Communications, 1971
Abstract Dielectric loss measurements on As 2 Se 3 glass samples at room temperature in the frequency region 10 2 – 10 10 Hz show losses considerable smaller than published values. Definite evidence for localized states was not found. An upper limit of 2 × 10 18 /cm 3 eV for the density of states at the Fermi level follows from these experiments.

Frequency-independent dielectric losses (1/f noise) in PLZT relaxors at low temperatures

, 2003
Dielectric properties of the relaxor ferroelectric ceramics PLZT 8/65/35 and 9.5/65/35 were studied in the broad frequency range of 100 Hz–1 THz at low temperatures below the freezing temperature.

Dielectric loss of insulating oil

Journal of the Institution of Electrical Engineers, 1953
Considerable discrepancies between the results of different laboratories when measuring the dielectric loss of the same insulating oils has been reported in co-operative tests for C.I.G.R.E., Second Series, 1949-50. These can arise either from contamination of the oil sample with impurities or from the instability of the oil.

Dielectric losses in ammonium fluorosilicates

Chemical Physics Letters, 1979
Abstract Cubic and trigonal (NH 4 ) 2 SiF 6 have low-temperature dielectric-loss maxima with activation energies E a (cubic) = 5.4 kcal/mol and E a (trig.) = 8.7 kcal/mol, not related to ionic reorientation and probably caused by OH − impurities.

Dielectric Loss in Rocks

1967
In alternating electric fields, a dielectric material is frequently characterized by its dielectric loss, which depends on the fraction of electrical energy lost to heat, rather than by its electrical conductivity. The energy loss occurs as the result of two processes: conduction and slow polarization currents.

Low Loss Dielectric Materials

2021
Semiconductor industry has identified five major growth engines (applications) [1, 2]: (1) mobile such as smartphones, smartwatches, notebooks, wearables, tablets, etc., (2) high-performance computing (HPC), also known as supercomputing, which is able to process data and perform complex calculations at high speeds on a supercomputer, (3) autonomous ...

DIELECTRIC LOSSES IN ISOTENAX N

Modern Physics Letters B, 2003
The limits of the Maxwell–Wagner model for interfacial losses in composite materials are discussed. The model is improved by taking into account the frequency dependence of the loss resistances. The improved model is applied to the statistical analysis of the experimental data obtained on Isotenax N. The results of the model are in very good agreement

Modelling of dielectric losses in microstrip patch antennas: application of FDTD method

, 1992
A frequency dependent complex permittivity is used to describe the dielectric losses of a microstrip patch antenna. The theoretical and experimental results for the usual parameters (input impedance, reflection coefficient and radiation pattern) of a ...

Dielectric loss anomaly of BaBiO3

Journal of Applied Physics, 1999
Dielectric properties of oxygen deficient BaBiO3−δ have been analyzed, and dielectric loss anomalies at 175 and 225 K were found, which were dependent on oxygen deficiency. The activation energies corresponding to the relaxation processes of dielectric anomalies at 175 and 225 K were 0.26 and 0.50 eV, respectively.

Relaxation in low-loss dielectrics

Journal of Molecular Liquids, 2000
Abstract The real and imaginary components of the complex susceptibility of the majority of non-polar dielectric materials follow a fractional power law dependence on frequency known as the “universal law”. One limiting form of this law shows a very low loss and also a nearly frequency-independent, or “flat” amplitudes.
