Abstract:
1. An apparatus for obtaining a dielectric constant and other measurements of a sample, comprising: an open cavity resonator; a microwave energy generator for creating a resonating microwave in the open cavity resonator; a predetermined dielectric material, the predetermined dielectric material being one of a liquid or gel having a high dielectric constant in the range of 2 to 100,000 substantially filling the region of the open cavity resonator in which a microwave resonates; the dielectric material adapted to receive a sample for measurement of the dielectric properties of the sample; whereby during operation the resonating microwave is substantially immersed in the predetermined dielectric material such that an effective electrical spot size and beam cross-section along a cylindrical axis of the resonating microwave is reduced as a function of the inverse of the square root of the predetermined dielectric material dielectric constant.
