摘要: We validate applicability of the known transmission-reflection (T/R) method to measuring complex permittivity seawater in broadband frequency range. consider a liquid sample that partly fills space coaxial test cell operating vertical position. The is plugged with single dielectric bead at bottom and thus has semi-open, versatile design. develop transfer matrix formulae for de-embedding from effects airline sections so as best fulfill assumptions T/R method. de-embedded scattering parameters let us analyze an asymmetry sample's reflection coefficients due meniscus formed top sample. Experimental results, obtained 7 mm coaxial-line fixture, evidence are negligible below 5 GHz. measured agrees very well data published elsewhere.
