20100134876 | WIRELESS SIGNAL PROXIMITY ENHANCER - A strongly anisotropic photonic crystal structure was designed using form birefringence. It has a low group velocity close to a split band edge (SBE) and large field enhancements proportional to the fourth power of the number of periods are predicted. The structure is used to amplify wireless signals outside and near the structure. | 06-03-2010 |

20110315219 | EFFICIENCY ENHANCEMENT OF SOLAR CELLS USING LIGHT MANAGEMENT - A photovoltaic cell includes a junction, formed from an n-type semiconductor material and a p-type semiconductor material, a trench, opening toward the light-incident side of the junction, for trapping reflected light, and two photon conversion layers. A first photon conversion layer, arranged at the light-incident side of the junction, converts photons from a higher energy to a lower energy suitable for absorption by the semiconductor material, and a second photon conversion layer, arranged at the opposite side of the junction, converts photons from a lower energy to a higher energy suitable for absorption by the semiconductor material. | 12-29-2011 |

20150017433 | COMPOSITE PLASMONIC NANOSTRUCTURE FOR ENHANCED EXTINCTION OF ELECTROMAGNETIC WAVES - The present disclosure explores and fabricates coupled plasmonic nanoparticles of gold (Au), silver (Ag), or aluminum (Al) onto nanorods or nanowires of zinc telluride (ZnTe), silicon (Si), germanium (Ge), or other semiconductor materials. Full-wave simulation is performed to obtain an optimum design for maximum light absorption. The nanorods, after being coated with a shell to form a p-n junction, or being imparted with a radial junction, are of interest for enhanced light harvesting in solar cells, for example. The fabrication method of such arrays is described. Modeling of the spectral properties using equivalent circuit theory is implemented to predict fabrication results and provide an intuitive approach regarding the design of these optical metamaterials with predetermined properties. | 01-15-2015 |
