3.4: Complex Permittivity - Physics LibreTexts

The relative permittivity of a material can be found by a variety of static electrical measurements. The complex permittivity is evaluated over a wide range of frequencies by using different variants of dielectric spectroscopy, covering nearly 21 orders of magnitude from 10 to 10 hertz. Also, by using cryostats and ovens, the dielectric properties of a medium can be characterized over an array of temperatures. In order to study systems for such diverse excitation fields, a number of measu… WebDielectric permittivity ε influences the magnitude of the electric field created by electric charges. The magnitude is inversely proportional to the dielectric permittivity. In free space, the permittivity is constant: ε 0 = 10 − 9/36π F m − 1.In insulators and polarizable material, such as geologic materials, the dielectric permittivity increases. WebPermittivity of free space, or vacuum, ( ε 0) is a constant value equal to 8.85 × 10 − 12 C N m 2. Mathematically, it can be obtained using the following equation: ε 0 = 1 μ 0 c 2, where μ 0 is vacuum permeability equal to 4 π × 10 − 7 T m A, and c is the speed of light 3.00 × 10 8 m s.
