Dielectric Susceptibility


a quantity characterizing the capability of a dielectric to be polarized. Quantitatively dielectric susceptibility equals the proportionality coefficient K in the relationship P = kE, where E is the intensity of the electric field and P is the polarization of the dielectric (the dipole moment per unit volume of the dielectric). The dielectric properties of a substance are characterized by dielectric susceptibility, as well as by its dielectric constant ∊. The relationship between these two properties is ∊ = 1 + 4πk.

Because of the dielectric susceptibility that determines the value of dQ (15), it is advisable to use the ferroelectric ceramics with the highest value of [partial derivative][epsilon]e/[partial derivative]T which is important for the electrocaloric heat transformers.
For a time-harmonic-field approximation, the effective dielectric susceptibility has the form
Figure 3 shows the real ([chi]') and imaginary ([chi]") parts of the complex dielectric susceptibility [chi] of polymer 2 at room temperature over a frequency range of 100 Hz to ~3 x [10.sup.5] Hz in the double-log plot.
