    Abstract: Methods and apparatus for examining a material are provided. One example method generally includes disposing the material in a dielectric contrast analysis structure, wherein the dielectric contrast analysis structure comprises a bulk dielectric substance and a plurality of receptacles in the bulk dielectric substance, wherein the material is disposed in one or more of the plurality of receptacles; exposing the dielectric contrast analysis structure to incident electromagnetic radiation; detecting resultant radiation from the exposed dielectric contrast analysis structure; and analyzing the detected resultant radiation to estimate at least one of a phase fraction and a phase distribution in the material. One example system generally includes an electromagnetic radiation source; a dielectric contrast analysis structure comprising a bulk dielectric substance and a plurality of receptacles in the bulk dielectric substance for receiving the material; and an electromagnetic radiation detector, wherein the analysis structure is between the radiation source and the detector.

    Abstract: A method for estimating a flow rate of a material (e.g., a multiphase fluid) may include: flowing the material through one or more of a plurality of receptacles of a dielectric contrast analysis structure that includes: a bulk dielectric substance and the plurality of receptacles in the bulk dielectric substance; exposing the dielectric contrast analysis structure to incident electromagnetic radiation; detecting and analyzing a resultant electromagnetic radiation from the exposed dielectric contrast analysis structure to yield a phase fraction in the material and a phase distribution in the material; measuring a differential pressure across the dielectric contrast analysis structure; and estimating the flow rate of the material using the differential pressure, the phase fraction, and the phase distribution in the material.
