University of Missouri--Kansas City, 2019In the radiofrequency bands, measuring the power-dependent complex permittivity
and permeability of materials that undergo metal–insulator transitions is a significant
challenge which is important for defense and commercial applications. This thesis attempts
to articulate barriers in the prior art, and how the techniques described herein overcome such
deficiencies. Specifically, using a combination of direct and indirect narrow-band resonant
and wide-band, non-resonant heterostructures, with narrow gaps, application relevant electric
fields were achieved, and complementary assessments of the measured S-parameters were
determined. The heterostructures/fixtures include complementary split-ring resonator and
coplanar waveguide instantiations. Additionally and complementary to the RF measurement
systems, a ferroelectric test measurement system for high-frequency and high-power
polarization vs. electric field curves was designed, built, tested, and shown to match baseline
comparisons. The ferroelectric test system is a Sawyer–Tower variant using the virtual
ground topology.Introduction -- Background -- Overview of measurement Techniques -- Coplanar waveguides and complementary split-ring resinators -- Virtual ground method -- Summary and future wor
