Relative Permittivity Measurement of Microliter Volume Liquid Samples through Microwave Filters
This paper proposes a concept of dielectric characterization of low-volume liquid samples using the coupling coefficient of filters. The concept is validated through a two-pole substrate integrated waveguide filter in which the liquid under test is mounted on the coupling section between the two res...
