abstract = "In this letter, we comment on the applicability of the derived
characteristic equation (Eq. (7)) in a recently published article
of Guoxin [Rev. Sci. Instrum. 86, 014704 (2015)]. To validate our
comment, we first derive another characteristic function for
determination of complex permittivity of dielectric materials for
the configurations considered in the above article using
calibration-independent uncorrected S-parameters for
transmission-line measurements (coaxial-line, waveguide,
free-space, etc). Unlike the characteristic equation in this
article, the characteristic equation derived here for
determination of the complex permittivity of liquid samples does
not require any knowledge about the complex permittivity of plugs,
used for holding liquid samples in place. We then performed 3-D
full-wave simulations for the measurement configurations presented
in Guoxin's article for substantiation of the characteristic
equation derived in this letter.",
