| 20090303154 | Apparatus for Sub-Wavelength Near-Field Focusing of Electromagnetic Waves - Planar sub-wavelength structures provide superlensing, i.e., electromagnetic focusing beyond the diffraction limit. The planar structures use diffraction to force the input field to converge to a spot on the focal plane. The sub-wavelength patterned structures manipulate the output wave in such a manner as to form a sub-wavelength focus in the near field. In some examples, the sub-wavelength structures may be linear grating-like structures that can focus electromagnetic radiation to lines of arbitrarily small sub-wavelength dimension, or two dimensional grating-like structures and Bessel (azimuthally symmetric) structures that can focus to spots of arbitrarily small sub-wavelength dimensions. The particular pattern for the sub-wavelength structures may be derived from the desired focus. Some examples describe sub-wavelength structures that have been implemented to focus microwave radiation to sub-wavelength dimensions in the near field. | 12-10-2009 |
| 20110209110 | Tensor Transmission-Line Metamaterials - Tensor transmission-line metamaterial unit cells are formed that allow the creation of any number of optic/electromagnetic devices. A desired electromagnetic distribution of the device is determined, from which effective material parameters capable of creating that desired distribution are obtained, for example, through a transformation optics/electromagnetics process. These effective material parameters are then linked to lumped or distributed circuit networks that achieve the desired distribution. | 08-25-2011 |

| 20120007791 | Antenna Fabrication with Three-Dimensional Contoured Substrates - Disclosed herein is a method of fabricating an antenna in which a flexible stamp is formed from a first wafer, the first wafer transferring a pattern to the flexible stamp, in which an antenna substrate is shaped into a three-dimensional contour with a second mold, in which the flexible stamp is positioned in the second mold to deform the flexible stamp into the three-dimensional contour, and in which a metallic layer on the flexible stamp is cold welded to create a set of antenna traces on the antenna substrate in accordance with the pattern. The antenna traces may then be electroplated. | 01-12-2012 |
