Relative permittivity of aluminum
The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field. Permittivity is a material's property that affects the Coulomb force between tw… WebJul 1, 2024 · Many works in these fields have been directed towards finding approximation formulae for the frequency-dependent effective permittivity (epsilon) of two component (scandium and aluminum) [10]. There are many theories used to model optical properties 'rice theory', finite-element, and effective medium (Fig. 2, Fig. 3, Fig. 4).
