1. A microwave dielectric analyzer, comprising:
a measurement apparatus having a single conductive electrode configured to couple to a microwave analyzer; and
processing circuitry configured to determine a dielectric characteristic of a dielectric specimen based upon a reflection coefficient measured by the microwave analyzer with the dielectric specimen in contact with the single conductive electrode, the dielectric characteristic determined based upon a computational electromagnetic model of the measurement apparatus.
