dielectric relaxationFluctuation formulas to calculate the temperature derivatives of the frequency-dependent dielectric constant are proposed and applied to a Stockmayer fluid using molecular dynamics simulati
A self-consistent computer adapted theory to calculate the wavevector- and frequency-dependent dielectric constant of polar fluids with permanent dipoles is proposed. The dielectric tensor of the Stockmayer fluid is evaluated in a wide region of wavevectors and frequencies using molecular dynamics ...
We have recently been able to find the general relation between frequency and electrical conductance and dielectric constant in mixtures.From our general equation of the force of relaxation one can now derive a detailed discussion of the quantitative limiting laws of the conductivity and the ...
We presented the research results by impedance spectroscopy of frequency-dependent temperature activation of the conductivity and dielectric constant of the single-crystal magnetoelectric bismuth ferrite BiFeO3, a promising functional material for RAM devices. The activation energies of low-temperature (110–...
The frequency dependence of conductivity and dielectric constant of glassy samples of (Na2B4O7)100-x(WO3)x′, where X=0, 1, 5, 15 and 30 mol % respectively, were measured in the temperature range 323–473 K. The a.c. conductivity σac(ω) is found to be proportional to ωS. The...
When a material system is exposed to an intense optical field E(ω), its optical properties such as dielectric constant can be modified by the applied field. Thus, the optical response of the material system is no longer in a linear relationship to the optical field. The polarization density...
