abstract = {This article presents a method for effectively characterizing
the dielectric permittivity of nematic liquid crystals (LCs)
across a broad frequency range. These materials show significant
potential for reconfigurable devices operating in microwave and
millimeter-wave frequencies. To achieve this goal, an additive
manufacturing technique is used to create a microstrip line that
can be filled with liquid that acts as its substrate. The LC is then
biased to modulate its permittivity. After manufacturing, a time-gating
approach is used to extract the permittivity, eliminating
the need for in-fixture calibration, such as thru–reflect–line
(TRL). Finally, the approach is validated through simulations
and experimental results, which closely align with those reported
using other methods in the bibliography.},
