Patent 11988557 was granted and assigned to BATTELLE SAVANNAH RIVER ALLIANCE, LLC on May, 2024 by the United States Patent and Trademark Office.
Methods and systems are described for use in determination of the presence, type (static or AC), direction, and/or strength of an electric field. Methods include examination of a gaseous sample to determine the presence of perturbation effects brought about by dielectrophoretic forces acting on components of the gaseous sample, and thereby, to identify the presence of an electric field. Examination of a gaseous sample can include Raman spectroscopy. A gaseous sample can be analyzed to determine the presence of molecular polarization due to an induced dipole on a polarizable molecule.
