Preferred Term:
dielectric spectroscopy
Definition:
A technique of measuring the dielectric properties of materials, which vary over a range of frequencies depending on the physical properties of the material. The technique involves measuring, over a range of frequencies, electrical impedance and phase shift of an electric field as it passes through the material.
