Permittivity | Absolute, Relative & Vacuum | Definition & Values
Permittivity - Absolute and Relative. In electromagnetism, permittivity, which is also known as absolute permittivity, is a measure of the electric polarizability of a dielectric or an insulator. The permittivity also characterizes the ability of the dielectric to store electric energy in an electrical field.

3.4: Complex Permittivity - Physics LibreTexts
An example of the complex permittivity of a typical dielectric material is shown in Figure 3.4.1 3.4. 1. Note the frequency dependence is quite simple and slowly-varying at frequencies below 1 GHz or so, but becomes relatively complex at higher frequencies. Figure 3.4.1 3.4. 1: The relative contributions of the real and imaginary components of ...

Complex Permittivity - an overview | ScienceDirect Topics
The complex permittivity spectrum of ethanol, Fig. 4, is typical for the dielectric response of liquids in the microwave region.The aim of DRS is the interpretation of the observed relaxation behavior on the molecular scale. Prerequisite of such an endeavor is the fitting of ɛ ˆ (v) by an appropriate model to extract the independent relaxation modes contributing to dielectric permittivity.

Relative permittivity
The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of permittivity of the material, and ε0 is the vacuum permittivity. wikipedia.org

Relative permittivity - Wikipedia
Relative permittivity is the factor by which the electric field between the charges is decreased relative to vacuum. Likewise, relative permittivity is the ratio of the capacitance of a capacitor using that material as a dielectric, compared with a similar capacitor that has vacuum as its dielectric. Relative permittivity is also commonly known ...
