The capability to measure the dielectric properties of various materials has been developed in the Electromagnetic Properties Measurement Laboratory (EPML) of the Electromagnetics Research Branch (ERB). Two measurement techniques which have been implemented in the EPML to characterize materials are the dielectric probe and waveguide by: Lab Setup and Measurements There are a host of methods for measuring the dielectric permittivity of a material. Here, we will describe two basic experiments. These experiments assume that 1) the sample is non-magnetic (i.e. $$\mu = \mu_0$$) and 2) the conductivity of the sample is sufficiently small (\(\sigma . Measurements of the dielectric properties of frozen cod have been carried out in the temperature range 0 to —30°C.   Dielectric loss tangent measurements reflect the different loss mechanisms occurring in a material place in an electric field. Because of all these factors, both measurement techniques and accuracies for evaluation of dielectric properties are requisite for physical : Richard G. Geyer, Jerzy Krupka.
