20100073232 | Wide Angle Impedance Matching Using Metamaterials in a Phased Array Antenna System - A phased array antenna system may include a sheet of conductive material with a plurality of aperture antenna elements formed in the sheet of conductive material. Each of the plurality of aperture antenna elements is capable of sending and receiving electromagnetic energy. The phased array antenna system may also include a wide angle impedance match (WAIM) layer of material disposed over the plurality of aperture antenna elements formed in the sheet of conductive material. The WAIM layer of material includes a plurality of metamaterial particles. The plurality of metamaterial particles are selected and arranged to minimize return loss and to optimize an impedance match between the phased array antenna system and free space to permit scanning of the phased array antenna system up to a predetermined angle in elevation. | 03-25-2010 |

20100289715 | Metamaterial particles having active electronic components and related methods - Metamaterial particles having active electronic components are disclosed. According to one aspect, a metamaterial particle in accordance with the subject matter disclosed herein can include a field sensing element adapted to sense a first field and adapted to produce a sensed field signal representative of the first field in response to sensing the first field. Further, the metamaterial particle can include an active electronic component adapted to receive the sensed field signal and adapted to produce a drive signal based on the sensed field signal. A field generating element can be adapted to receive the drive signal and adapted to produce a second field based on the drive signal. | 11-18-2010 |
