We discuss the derivation of the carrier concentration n and mobility of thin films from transmission and reflection in the far-infrared, through the expression of the dielectric constant when plasmon-phonon co
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 ...

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...
The field dependence of the dissipation factor peak in triglycine sulphate, previously investigated at 1 kHz, has been studied in a wide frequency range from 20 Hz to 1 MHz. The frequency dependence observed is fairly complex in this range, being affected by piezoelectric resonances at about ...

But a physical description of the MWS mechanism has remained a challenge. This is the main objective of this study. It will be shown that the MWS mechanism not only has great influence to the observed high dielectric constant, but also to the frequency dependence of electrical conductivity and...
