abstract = "We propose a non-resonant-type method for reference-plane
invariant and thickness-independent permittivity measurement of
solid dielectric materials when there is no information from
permittivity. To achieve this, we derive a
branch-index-independent function and verify that it determines
the sample thickness and permittivity without resorting to finding
the correct branch index value for three different measurement
scenarios: (a) measurements at closely separated frequencies of
non-dispersive samples, (b) measurements at largely separated
frequencies of non-dispersive samples, and (c) measurements at
largely separated frequencies of dispersive samples. Via a
differential uncertainty analysis, the effect of inaccurate sample
thickness on permittivity determination is also presented for
demonstration of the improvement achieved by our method. For
validation, we measured the permittivity of an approximately 20 mm
PTFE sample using the presented method and compared its result
with those from other similar methods. From the comparison, we
note that the accuracy of tested methods from literature
drastically decreases when accurate information of sample
thickness is not known (in addition to a further decrease in
accuracy when correct transformation factors from reference-planes
are not known a priori), while the accuracy of our method is not
influenced.",
