The dielectric constant
describes the electrical properties of the material influencing the propagation of waves in the range 10 MHz to 1,000 MHz (Davis and Annan 1989).
and tangent loss showed normal dispersion behavior.
and relative dielectric constant
of EVA/Pani composites with respect to variation in pressure have been shown in Figs.
At higher frequencies the electron exchange between ferrous and ferric ions cannot follow the alternating field, which causes a decrease in the contribution of interfacial polarization in dielectric constant
, and as a result, we see a decrease in the dielectric constant
and dielectric loss factor.
It is not possible to calculate a dielectric constant
Temperature dependent dielectric constant
has been studied within the temperature range from 40 to 200 degC with fixed frequency of 100 kHz.
Variation of dielectric constant
, volume resistivity, and electrical conductivity of the composites with respect to different frequencies and temperatures are reported.
To first order, you would not think dielectric constant
influences the coupling.
The Maxi-Plus Series of single layer capacitors exhibits a dielectric constant
Recently the step curing and continuous curing techniques involving measurement of electrical properties like dielectric constant
, loss factor, are also reported in the literature (refs.
Symyx's patented tuning fork technology, developed as a single-sensor platform, has direct application for providing real-time, in-situ measurements and monitoring of the viscosity, density, and dielectric constant
of oils, lubricants, refrigerants, fuels, solvents, gases and other single and multiphase fluid mixtures.
Dielectric measurements were carried out for all the samples prepared in pallets form to find out the dielectric parameters such as dielectric constant
and dielectric loss as function of frequency.
