Web15. apr 2009 · ε'' is the dielectric loss factor. The dielectric loss factor is a function of conductivity and frequency: ε'' = σ/ (2∏f) Where: ω = 2∏f. So the permittivity can be expressed as a function of the dielectric constant and the conductivity: ε = ε' - jσ/ω. The concept of conductivity in a dielectric manifests itself in a description of ... In electromagnetism, the absolute permittivity, often simply called permittivity and denoted by the Greek letter ε (epsilon), is a measure of the electric polarizability of a dielectric. A material with high permittivity polarizes more in response to an applied electric field than a material with low permittivity, thereby storing more energy in the material. In electrostatics, the permittivity pl…
