Application and Theory of Dielectric Materials in RF/Microwave Systems

In the broad sense, dielectrics are materials that can influence and be influenced by the electric portion of an electromagnetic field. While all objects exhibit dielectric properties to differing degrees, this paper will concern itself with simple dielectric materials with low conductivity anno ‘semi-conducting’ properties. Also, certain dielectrics have high loss and are used to attenuate a propagating wave. These dielectric absorbers will not be treated in this paper.
