The results showed that the relative dielectric constant of pork was decreased with increasing frequency, and the dielectric loss factor reached a minimum at 2500MHz. The relation between the dielectric constant of the solvent and the dissociation constant of Glycine was... On decreasing capacitance,...

J.Ilic, inEncyclopedia of Materials: Science and Technology, 2001 2.2Density Thedielectric constantof wood increases in direct proportion with density. As the frequency increases the dielectric constant diminishes, since fewer of the polar wood molecules have sufficient time to follow the external field...
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 the dielectric constant shows that this process is something like a resonance polarization in the materials. (3) The dielectric behavior at temperatures around the temperatures of the dielectric constant maximum is determined with both polarization processes. The micro-origin ...

In electrical engineering and electronics, the dielectric losses are characterized by the loss tangent: tanδ. However, the most general physical characteristic of losses, particularly for description of frequency dependences, is the complex dielectric constant: ɛ∗ω=ɛ′ω−ɛ″ω,tanδ=...
