  • Method for modeling an information capacity of a multiantenna wireless system
    Patent number: 6782257
    Abstract: Methods of designing, installing and operating communications systems including multiple input multiple output (MIMO) antenna arrays are disclosed. The methods account for the diffusive nature, the polarization nature, and the multi-path nature of the environment in which the antenna arrays operate. According to the various methods, the antennas can be designed, installed and operated so as to provide improved information capacity based on the diffusive, polarization and multi-path nature of the environment in which they operate.

  • Design, fabrication and operation of antennas for diffusive environments
    Patent number: 6501963
    Abstract: A method of designing, fabricating and operating antennas is disclosed that considers the diffusive nature of the environment in which the antennas are to operate. Furthermore, the antennas can be designed, fabricated and operated so as to provide the optimal channel capacity possible given the diffusive nature of the environment in which they are to operate. The illustrative embodiment of the present invention comprises: describing an environment; describing a candidate antenna; determining a performance characteristic based on the candidate antenna with respect to the environment; and fabricating a first antenna in accordance with the candidate antenna.

  • Optical waveguide gratings having roughened cladding for reduced short wavelength cladding mode loss
    Patent number: 6408118
    Abstract: In accordance with the invention, an optical waveguide comprising a longitudinally extending core housing an optical grating and a cladding layer peripherally surrounding the core, is provided with an outer surface of the cladding layer having one or more perturbations. Each perturbation has a height with respect to the core that varies by at least 0.1 times a Bragg wavelength of the grating over the surface of the perturbation and covers an extent of the outer surface whose linear dimensions are less than 1 cm. The perturbations suppress cladding mode spectra and reduce short wavelength cladding mode loss.
