Patents by Inventor Mohammad MOJAHEDI

Mohammad MOJAHEDI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10190981
    Abstract: Apparatuses and methods for spectroscopy using multiple resonance modes are provided. Multiple resonance modes may be used for bulk sensing and/or surface sensing applications. A plasmon waveguide resonance sensor is provided for multimode spectroscopy. The sensor includes a dielectric layer; and a metallic layer coupled to the dielectric layer. The sensor is configured to provide: a first resonance mode for bulk sensing, in response to light of a given wavelength; and a second resonance mode for surface sensing, in response to light of the given wavelength. The first and second resonance modes have different polarizations. Surface plasmon resonance assemblies are provided having a grating coupled to a surface plasmon resonance sensor, the grating being a dielectric grating or a metallic grating. The grating, in response to light, provides various resonance modes having at least two different polarizations for bulk and surface sensing.
