Gw. Hanson et al., AN IMPROVED DE-EMBEDDING TECHNIQUE FOR THE MEASUREMENT OF THE COMPLEXCONSTITUTIVE PARAMETERS OF MATERIALS USING A STRIPLINE FIELD APPLICATOR, IEEE transactions on instrumentation and measurement, 42(3), 1993, pp. 740-745
A method for measuring the electromagnetic constitutive parameters of
materials using a strip transmission-line field applicator is presente
d. A technique is developed to measure the scattering parameters of th
e imperfect transition regions between the applicator coaxial terminal
ports and the front and back terminal planes of the material sample i
n strip-line. S-parameters of the sample region are subsequently de-em
bedded from the coaxial-terminal S-parameters using the measured trans
ition-region network model. The complex permittivity and permeability
of the sample are easily related to the sample's S-parameters through
well known analytic relations. Measured constitutive parameters are pr
esented for several representative materials.
