6 Techniques for Measuring Dielectric Properties

In general materials can be classified into conductors, semiconductors and insulators or dielectric materials. Dielectric materials play an important role in our daily life especially every electronic circuit, which needs a dielectric medium to build the circuit. Typically high frequency electronics circuits are built on dielectric materials and the operation of all high frequency circuits depends on the dielectric properties of the material. In order to design high frequency circuits it is essential to have vital understanding of the properties of the dielectric materials especially the dielectric constant (real part of complex permittivity) and loss tangent at the operating conditions. Dielectric ...
