Measurements of electromagnetic properties of dielectric materials in the microwave range

Abstract

In this work the theory, analysis and a practical implementation of a method of measurement of relative dielectric permeability /spl epsiv/*=/spl epsi/-i/spl middot//spl epsiv/" of materials in a frequency range from 0.5 up to 25 GHz is considered. Values of /spl epsi/ were measured in a range from 2 up to 200 relative units and values of dielectric losses tg/spl delta/ (/spl epsiv/"//spl epsi/) in a range from 5/spl middot/10/sup -5/ up to 2/spl middot/10/sup -2/.
