A dielectric materials measurement can provide critical design parameter information for many electronics applications. For example, the loss of a cable insulator, the impedance of a substrate, or the frequency of a dielectric resonator can be related to its dielectric properties.
Measurement of dielectric properties involves measurements of the complex relative permittivity (:r) and complex relative permeability (<r) of the materials. A complex dielectric permittivity consists of a real part and an imaginary part.
Dielectric breakdown leads to catastrophic failure, while dielectric loss can be managed through design. Dielectric loss occurs because real capacitors have resistive components that dissipate energy as Joule heat, reducing the ideal phase difference between current and voltage.
The loss angle δ is equal to (90 – θ)°. The phasor diagrams of an ideal capacitor and a capacitor with a lossy dielectric are shown in Figs 9.9a and b. It would be premature to conclude that the Dielectric Constant and Loss material corresponds to an R-C parallel circuit in electrical behaviour.
The dielectric material increases the storage capacity of the capacitor by neutralizing charges at the electrodes, which ordinarily would contribute to the external field. The capacitance with the dielectric material is related to dielectric constant.
