  • Patent number: 11726233
    Abstract: An optical sensor system, comprising refractory plasmonic elements that can withstand temperatures exceeding 2500° C. in chemically aggressive and harsh environments that impose stress, strain and vibrations. A plasmonic metamaterial or metasurface, engineered to have a specific spectral and angular response, exhibits optical reflection characteristics that are altered by varying physical environmental conditions including but not limited to temperature, surface chemistry or elastic stress, strain and other types of mechanical load. The metamaterial or metasurface comprises a set of ultra-thin structured layers with a total thickness of less than tens of microns that can be deployed onto surfaces of devices operating in harsh environmental conditions. The top interface of the metamaterial or metasurface is illuminated with a light source, either through free space or via an optical fiber, and the reflected signal is detected employing remote detectors.

  • Patent number: 10497416
    Abstract: A spintronic memory device having a spin momentum-locking (SML) channel, a nanomagnet structure (NMS) disposed on the SML, and a plurality of normal metal electrodes disposed on the SML. The magnetization orientation of the NMS is controlled by current injection into the SML through normal metal electrode. The magnetization orientation of the NMS is determined by measuring voltages across the NMS and the SML while flowing charge current through the SML via the normal metal electrodes.
