  • Publication number: 20200249451
    Abstract: Dielectric resonators provide a building block for the development of low-loss resonant metamaterials because they replace lossy ohmic currents of metallic resonators with low-loss displacement currents. The spectral locations of electric and magnetic dipole resonances of a dielectric resonator can be tuned by varying the resonator geometry so that desired scattering properties are achieved.

  • Patent number: 10590280
    Abstract: A waterborne basecoat includes a rheology package having two or more rheology modifiers selected from the group of an ethylene vinyl acetate copolymer wax emulsion, an alkali swellable acrylic copolymer emulsion, a silicate layered clay, and a hydrophobically modified ethylene oxide urethane; a resin system comprising two or more waterborne dispersion resins selected from the group of a urethane-acrylic hybrid resin dispersion having a medium Tg of about 15 to about 35° C., a urethane modified Aldehyde/ketone emulsion having a high Tg of more than about 100° C., and a polyurethane dispersion having a low Tg of less than about ?20° C., and a pigment. The pigment may be metallic or non-metallic and may be selected from organic or inorganic pigments. The rheology package and the resin package may be optimized to accommodate properties commonly associated with different types of known pigments.

  • Patent number: 10572786
    Abstract: A reflective particle tag reader system includes a read head assembly having a camera, illuminators, and a rigid frame portion for supporting the camera and the illuminators. The illuminators illuminate a focal point located opposite the camera where a reflective particle tag is placed. A computer in data communication with the camera receives and store images of the reflective particle tag that are acquired by the camera. The computer is programmed to process video images and to quantify a positional alignment parameter and an angular alignment parameter of the reader with respect to the reflective particle tag. A rapid burst of image frames is obtained in response to the positional alignment and the angular alignment parameters being within a predetermined tolerance and identity of the reflective tag is established between a first image set and a second image set.

  • Patent number: 10393933
    Abstract: Tunable filters can use Fano metasurface designs having extremely narrow transmission bands. The Fano metasurface can comprise dielectric or semiconductor materials and can produce transmission bands with quality factors well in excess of 1000—at least a factor of 50 greater than typical metamaterial-based infrared resonances. Numerical simulations of these metasurfaces show that the spectral position of the passband can be changed by slightly changing the position of a small dielectric perturbation block placed within the near-field of the resonator by using simple electromechanical actuation architectures that allow for such motion. An array of independently tunable narrowband infrared filters can thereby be fabricated that only requires deep-subwavelength motions of perturbing objects in the resonator's near-field.

  • Patent number: 10361250
    Abstract: An array of dielectric resonators is formed on a substrate. Each resonator includes an active medium having an optical transition that is operative in a process of photodetection or photoemission. The active media each include a quantum well multilayer. The dielectric resonators in the array are each dimensioned to provide a resonance that lies substantially at the frequency of the optical transition.

  • Publication number: 20190196229
    Abstract: Thermochromic low-emissivity films can comprise a vanadium dioxide thin film or a thin film of vanadium dioxide nanoparticles incorporated into a polymer matrix, and a layer comprising a transparent conductive oxide to modify solar heat gain, solar reflectivity and thermal resistance of windows. The thermochromic low-emissivity films transition from infrared (IR) reflective when warm, to IR transparent when cool. This dynamic reflectivity is passive by nature, and requires no electronics or power source to shift. In addition, this dynamic transition can occur at any design temperature, and when the nanoparticles are dispersed, they remain transparent in the visible spectrum during both phases.

  • Patent number: 10180398
    Abstract: A hyperspectral imaging flow cytometer can acquire high-resolution hyperspectral images of particles, such as biological cells, flowing through a microfluidic system. A trajectory-based triggering system can be used that will only trigger the acquisition of a hyperspectral image when an appropriate particle or cell is crossing an imaging line, thereby saving valuable resources and time. The hyperspectral imaging flow cytometer can provide detailed spatial maps of multiple emitting species, cell morphology information, and state of health. An optimized system can image about 20 cells per second. The hyperspectral imaging flow cytometer enables many thousands of cells to be characterized in a single session.

  • Patent number: 10054839
    Abstract: A method of nonlinear wavelength generation uses a nonlinear optical medium. An input flux of pump energy is applied to one or more dielectric optical resonators. Each resonator has an optical cavity comprising the nonlinear optical medium. Each resonator has at least one Mie resonance that is excited by the input flux of pump energy. The pump energy causes the generation of converted light containing at least one converted component having a frequency attainable only through a non-linear process.

  • Patent number: 9909233
    Abstract: The present invention pertains to the use of mobile coherent interfaces in a ferroelectric material to interact with optical phonons and, ultimately, to affect the material's optical properties. In altering the optical phonon properties, the optical properties of the ferroelectric material in the spectral range near-to the phonon mode frequency can dramatically change. This can result in a facile means to change to the optical response of the ferroelectric material in the infrared.

  • Patent number: 9846348
    Abstract: Efficient harmonic light generation can be achieved with ultrathin films by coupling an incident pump wave to an epsilon-near-zero (ENZ) mode of the thin film. As an example, efficient third harmonic generation from an indium tin oxide nanofilm (?/42 thick) on a glass substrate for a pump wavelength of 1.4 ?m was demonstrated. A conversion efficiency of 3.3×10?6 was achieved by exploiting the field enhancement properties of the ENZ mode with an enhancement factor of 200. This nanoscale frequency conversion method is applicable to other plasmonic materials and reststrahlen materials in proximity of the longitudinal optical phonon frequencies.

  • Patent number: 9799798
    Abstract: A novel thermal source comprising a semiconductor hyperbolic metamaterial provides control of the emission spectrum and the angular emission pattern. These properties arise because of epsilon-near-zero conditions in the semiconductor hyperbolic metamaterial. In particular, the thermal emission is dominated by the epsilon-near-zero effect in the doped quantum wells composing the semiconductor hyperbolic metamaterial. Furthermore, different properties are observed for s and p polarizations, following the characteristics of the strong anisotropy of hyperbolic metamaterials.

  • Patent number: 9685765
    Abstract: A new monolithic resonator metasurface design achieves ultra-high Q-factors while using only one resonator per unit cell. The metasurface relies on breaking the symmetry of otherwise highly symmetric resonators to induce intra-resonator mixing of bright and dark modes (rather than inter-resonator couplings), and is scalable from the near-infrared to radio frequencies and can be easily implemented in dielectric materials. The resulting high-quality-factor Fano metasurface can be used in many sensing, spectral filtering, and modulation applications.
