Precision waveguide system for measurement of complex permittivity of liquids at frequencies from 60 to 90 GHz.

Abstract

We describe a variable path length waveguide setup developed to accurately measure the complex dielectric permittivity of liquids. This is achieved by measuring the complex scattering parameter of the liquid in a waveguide section with a vector network analyzer in combination with an E-band frequency converter. The automated measurement procedure allows… (More)
