Abstract : An analytical solution for the intrinsic impedance of a material is applied to a method of measuring the dielectric and loss tangent with the use of a coaxial test fixture and a vector network analyzer. The use of the equations is best suited for determining the electrical properties of lossy dielectrics over large frequency ranges. The method is unique in that it is not a numerical technique nor does it neglect reflections from any of the material surfaces.
