Dielectric constant variation with frequency

WebAug 27, 2024 · The dielectric frequency is the change in the properties of dielectrics due to changes in the frequency of an electric field. The ability of a dielectric to store energy really depends on the frequency of the electric field that is applied at any given moment. This phenomenon is known as dielectric dispersion. How it is measured: WebNov 26, 2024 · At sufficiently high frequencies (above ~10 15 Hz), none of the polarisation mechanisms are able to switch rapidly enough to remain in step with the field. The material no longer possesses the ability to polarise, and the dielectric constant drops to 1 – the …
