Publication number: 20230366809Abstract: A method for determining at least one property of magnetic matter includes: applying a magnetic field to magnetic matter; directing first light on the magnetic matter at a first set of incident angles; receiving a first set of signatures associated with the first light scattered from the magnetic matter; varying orientation of the magnetic matter with respect to the magnetic field; directing second light on the magnetic matter at a second set of incident angles; receiving a second set of signatures associated with the second light scattered from the magnetic matter; determining, by processing the first set and the second set of signatures according to a dispersion relation, at least one property of the magnetic matter.Type: ApplicationFiled: September 4, 2021Publication date: November 16, 2023Inventors: Justin M. SHAW, Thomas J. SILVA, Hans Toya NEMBACH, Grant A. Riley

Publication number: 20140209683Abstract: A method and apparatus for identifying an object having a pattern of plasmon resonant particles (PREs) distributed in or on the object are disclosed. In the method, a field containing the pattern is illuminated, and one or more spectral emission characteristics of the light-scattering particles in the field are detected. From this data, an image of positions and spectral characteristic values in the field is constructed, allowing PREs with a selected spectral signature to be discriminated from other light-scattering entities, to provide information about the field. The image may be compared to a database of reference images to identify or validate the object.Type: ApplicationFiled: March 26, 2014Publication date: July 31, 2014Applicant: The Regents of the University of CaliforniaInventors: Sheldon Schultz, David A. Schultz, David R. Smith, Jack J. Mock, Thomas J. Silva

Patent number: 8309370Abstract: A method and apparatus for interrogating a target having a plurality of plasmon resonant particles (PREs) distributed in the target are disclosed. In the method, a field containing the target is illuminated, and one or more spectral emission characteristics of the light-scattering particles in the field are detected. From this data, an image of positions and spectral characteristic values in the field is constructed, allowing PREs with a selected spectral signature to be discriminated from other light-scattering entities, to provide information about the field. Also disclosed are a novel PRE composition for use in practicing the method, and a variety of diagnostic applications of the method.Type: GrantFiled: June 9, 2011Date of Patent: November 13, 2012Assignee: The Regents of The University of CaliforniaInventors: Sheldon Schultz, David A.
