Measurement of the effective relative permittivities of microstrip
Electronics Letters, 1975 A new method for determining the effective relative permittivity of microstrip, even at high frequencies, is presented. Four microstrips having the same physical and geometric characteristics, but different lengths, are needed; the mismatch due to the launchers is completely overcome.

A Broadband Stripline Technique for Characterizing Relative Permittivity and Permeability [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2018 We present a stripline design and calibration method allowing the extraction of relative permittivity of single dielectric samples in the 200-MHz–50-GHz range. The simultaneous extraction of relative permittivity and permeability is also illustrated by characterizing a set of samples comprising magnetic inclusions over the same frequency range.

Determination of the Permittivity of Transmission Lines at Milli-Kelvin Temperatures
IEEE Access, 2023 Many quantum technologies rely heavily on propagation of RF and microwave signals through devices at cryogenic temperatures, and detailed understanding of materials and signal propagation is therefore key to improving the performance of quantum circuits.
