The broadband device for nondestructive measurements of dielectric permeability of lossy media

The opportunity of creation of the device and a corresponding method for measurement of complex dielectric permeability of solid, liquid, loose environments in ultra short wave and in microwave ranges without breaking of their structure is investigated. The given problem is actual in many areas, including geophysics, radio physics, underground radio sounding and the like. For nondestructive materials testing it is necessary to use only flat constructions of the measuring cell, for example, as unbalanced strip line (SL), slot line or coplanar waveguide. Use of shielded coplanar waveguide (SCPW) as a measuring cell of the complex dielectric permeability tester is base. Results of development of a broadband Instrument on basis SCPW for measuring an electrical parameters of lossy materials, methods of its calibration and testing are presented.
