Abstract: Embodiments of the present disclosure pertain to transmission dielectric probes with at least one channel that extends across the probe. The channel includes a first opening on a first side of the transmission dielectric probe, and a second opening on a second side of the transmission dielectric probe. The first opening and the second opening are on opposite ends of the transmission dielectric probe, and the second opening is associated with an outer surface of the transmission dielectric probe. Additionally, the first opening and the second opening have different diameters, different geometries, or combinations thereof. Further embodiments pertain to methods of operating the transmission dielectric probes by placing the outer surface of the transmission dielectric probe on a surface of an object, transmitting a signal from a first channel through the surface and into the object, and receiving the transmitted signal back through a second channel.

Abstract: A system for dielectric testing of wine in a bottle includes (a) a coaxial probe for interrogating the wine, wherein the coaxial probe has an open end for contacting an exterior surface of the bottle, and (b) a measurement module for determining a dielectric property associated with the wine by generating and measuring radio waves propagating through the coaxial cable. A method for dielectric testing of wine in a bottle includes measuring a radio-wave reflection signal associated with the wine by interrogating the wine, through the bottle, with radio waves, and determining a dielectric property associated with the wine from the radio-wave reflection signal. A probe for radio-wave interrogation of wine in a bottle has an inner conductor, an outer conductor, and an open end with curvature matching the curvature of an exterior surface of the bottle.

Abstract: A non-invasive microwave analysis method determines scattered phase and/or amplitude data for a liquid in a container. A transmitter antenna transmits microwaves that scatter from the container and the liquid in the container. One or more receiver antennas convert the microwaves into microwave electronic signals that are processed to determine the scattered phase and/or amplitude data. Another non-invasive microwave screening method includes placing a container of an unknown liquid in a tank. The container is separated by a membrane from coupling liquid in the tank. Microwave radiation transmits from a transmitter antenna and scatters from the container and the unknown liquid. One or more receiver antennas convert the microwave radiation into microwave electronic signals. The microwave electronic signals are processed to determine scattered phase and/or amplitude data. A pass result or a fail result is determined based on the scattered phase and/or amplitude data.
