A method to detect the presence and or concentration of an analyte in the environment of a spoof plasmon sensor having the steps of: providing a spoof plasmon sensor into an environment; interrogating said spoof plasmon sensor with an electromagnetic signal; collecting a modified electromagnetic signal from the spoof plasmon sensor; and analyzing the modified electromagnetic signal to detect an analyte in the environment of the sensor. A spoof plasmon sensor for detecting an analyte having a substrate with a superior surface; and a conductive material disposed on said superior surface, said conductive material defining a waveguide having a dual tapering shape, wherein said waveguide defines spoof plasmon cavities which are exposed substrate, where said substrate is configured to change in permittivity when contacted by an analyte.

Plasmonic microwave metamaterial waveguide sensing

The invention provides a method for measuring the magnetic field of an electromagnetic component having the steps of: instrumenting one or more portions of an electromagnetic component by placing an optical fiber in electromagnetic communication with the one or more portions of said electromagnetic component; energizing the electromagnetic component; interrogating the optical fiber using light and an optical detector; and determining changes in the magnetic field incident on the optical fiber based on the detected changes in the light received by the optical detector.

Gas sensor and method of optimizing an array of gas sensors

Materials, methods of making, and methods of using an integrated wireless detector for real time interrogating metallic tubular structures comprising: an RF patch antenna; a passive surface acoustic wave (SAW) sensor; and data analytic methodologies. An embodiment relates to interrogating a metallic structure having a uniform cross section using an antenna which launches electromagnetic radiation. A sensor may be located within the structure is configured to re-emit electromagnetic radiation modified depending on parameters for which the sensor has been functionalized. An antenna may receive radiation as modified by the sensor, or may receive the transmitted or backscattered radiation directly, without use of a sensor. The antenna then communicates wirelessly with an interrogator providing data which may be used to understand the operational status of the structure in real-time.
