WebThe 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 … The component ε′ represents the familiar lossless permittivity given by the product of the free space permittivity and the relative real/absolute permittivity, or ′ = ′. Loss tangent. The loss tangent is then defined as the ratio (or angle in a complex plane) of the lossy reaction to the electric ...
