Method And Apparatus For Electrical Cable Testing By Pulse-Arrested Spark Discharge
US Patent:
6853196, Feb 8, 2005
Filed:
Apr 12, 2002
Appl. No.:
10/122448

International Classification:
G01R031/11

G01R027/32

G01R027/32
US Classification:
324543, 324533, 324532, 324644, 324535, 324534
Abstract:
A method for electrical cable testing by Pulse-Arrested Spark Discharge (PASD) uses the cable response to a short-duration high-voltage incident pulse to determine the location of an electrical breakdown that occurs at a defect site in the cable. The apparatus for cable testing by PASD includes a pulser for generating the short-duration high-voltage incident pulse, at least one diagnostic sensor to detect the incident pulse and the breakdown-induced reflected and/or transmitted pulses propagating from the electrical breakdown at the defect site, and a transient recorder to record the cable response. The method and apparatus are particularly useful to determine the location of defect sites in critical but inaccessible electrical cabling systems in aging aircraft, ships, nuclear power plants, and industrial complexes.
High Quality-Factor Fano Metasurface Comprising A Single Resonator Unit Cell

G02B 1/00
H01S 5/10

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.
Flat Optics Enabled By Dielectric Metamaterials
US Patent:
2016015, Jun 2, 2016
Filed:
Jan 21, 2016
Appl. No.:

International Classification:
H01P 7/10
Abstract:
Metasurfaces comprise a two-dimensional periodic array of single-resonator unit cells. Single or multiple dielectric gaps can be introduced into the resonator geometry in a manner suggested by perturbation theory, thereby enabling overlap of the electric and magnetic dipole resonances and directional scattering by satisfying the first Kerker condition. The geometries suggested by perturbation theory can achieve purely dipole resonances for metamaterial applications such as wave-front manipulation with Huygens' metasurfaces.
