Measurement of Frequency Dependent Dielectric Properties by the Capacitance Technique

Measurement model of a capacitor designed for nondestructive testing (NDT) of dielectric materials in a frequency range is proposed. The capacitor, which is a source of electric field, fulfills also functions of a sensor. Proposed design involves electrodes, which are placed on the surface of a test objects, and therefore, secures unilateral access for testing. Particular case with electrodes of the capacitor located in one plane is discussed more in details.
