Abstract: An optical antenna collects, modifies and emits energy at light wavelengths. Linear conductors sized to correspond to the light wavelengths are used. Nonlinear junctions of small dimension are used to rectify an alternating waveform induced upon the conductors by the lightwave electromagnetic energy. The optical antenna and junctions are effective to produce harmonic energy at light wavelengths. The linear conductors may be comprised of carbon nanotubes that are attached to a substrate material, which may then be connected to an electrical port.

Abstract: The present invention comprises a docking system for connecting a portable communication device to a further signal transmission line. The docking system may be arranged within a workstation such as a desk or a tray. The system may also envelope a room in a building or be located in a vehicle, to control and restrict the radiative emission from the communication device and to direct such radiation to a further remote antenna and or signal distribution system connected to the transmission line.

Abstract: A method of providing wireless communication to a personal communication device in an rf restricted environment. The personal communication device has a radiative antenna. The method comprising: providing a personal communication device with a radiative antenna; providing a first coupler antenna within the rf restricted environment; connecting the first coupler antenna to a second antenna mounted on the outside of the rf restricted environment through a computer controlled circuit arranged therebetween; wirelessly connecting the first coupler antenna with the radiative antenna of the personal communication device within the rf restricted environment; monitoring communications of the personal communication device at any point between the first coupler antenna and the second antenna; and billing for use of the personal communication device within the rf restricted environment. The personal communication device may be a cellular telephone. The personal communication device may be a laptop computer.
