Patents by Inventor Vishwanath Iyer

Vishwanath Iyer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10275547
    Abstract: Methods and systems are presented for evaluating performance of a finite or infinite antenna array including a finite number of antennas. Typically, a model is generated for the antenna array, the model including an arbitrarily large antenna array with an arbitrarily large number of model antennas. Each model antenna has features defined by features of antennas of the finite or infinite antenna array. A unit cell is determined for the arbitrarily large antenna, and impedance matrices Zantenna and Zperiodic are computed, Zperiodic representing interactions among the unit cell and the other model antennas. From these matrices, the performance of the finite or infinite antenna array is assessed.

  • Patent number: 8384247
    Abstract: A system exchanges energy wirelessly and includes a source configured to generate evanescent waves, in response to receiving the energy, on at least part of a surface of the source. The system also includes a sink configured to receive the energy wirelessly from the source via a coupling of the at least part of the evanescent waves and a load configured to receive the energy from the sink. The load and the sink are configured to move along the surface of the source such that the at least a part of the evanescent waves are coupled between the source and the sink within an energy transfer area.
