Measuring complex permittivity and permeability with partially filled waveguide

摘要

A partially filled waveguide is used to measure complex permittivity and permeability simultaneously at microwave in this paper. A waveguide partially filled with material under test is measured by an automatic network analyser. The "mode match" method is used to analyse the higher order mode in the waveguide. Both theoretical and experimental aspects are discussed in detail. Experimental results agree well with the theoretical results.
