Dear All,

      Dielectric measurements are an important means of studying the dynamics properties (capacitance, conductance, permittivity and loss factor) of a dielectric. However, Dielectric measurements can be performed over a wide frequency range. My question is as given below:

What is the advantage of performing dielectric measurements in the frequency range from 42 Hz to 5 MHz (Audio- Radio frequency) in terms of its application point of view? I would be grateful to you if you could provide some references. 

Thanks in advance.
