“…The work in involves microstrip but places the microfluid above the microstrip trace in the fringing fields, which is convenient for assembly but does little to improve field overlap with the fluid. The work of does use a buried fluidic channel under a microstrip, but is principally a resonant technique rather than a broadband characterization, and a comparison to CPW is not made available. Here, we present an analysis of the broadband characterization of the complex permittivity of a microfluid embedded between the trace and ground of a microstrip.…”

A novel configuration for estimating the broadband permittivity of small fluid volumes is presented using 2‐port S‐parameters. Unlike previous demonstrations in coplanar technology, our proposal places the analyte under a microstrip trace where better field overlap with the fluid improves device sensitivity. Fluid parameter estimates based on simulation are presented. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2604–2608, 2014

This paper reports on dielectric properties of ternary mixtures involving sodium chloride (NaCl) and sucrose (C12H22O11) dissolved into water (H2O). Broadband electromagnetic characterizations of such mixtures at various concentrations were performed, evidencing a dual behavior made of conductive effects at low frequencies and dipolar relaxation at microwave frequencies. Conductive and dielectric properties resulting from these both effects were integrated into predictive models for variations of Cole–Cole model parameters. Based upon this modelling, an innovative microwave-based sensor able to retrieve concentrations of both sodium chloride and sucrose in ternary aqueous solutions was introduced, designed, realized and assessed. The proposed sensor shows an error lower than 5.5% for concentration ranges of 0 to 154 mmol/L for sodium chloride and 0 to 877 mmol/L for sucrose.
