WebAluminum Oxide is the standard dielectric material serving as gas barrier between vacuum of accelerating cavities and transmission line gas atmosphere which allows high RF power transmission as well. For proper design of RF power couplers it is important to know the actual material dielectric behaviour given by dielectricity 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… born free a new adventure 1996
