  • Method and Apparatus for Generating Electromagnetic Beams
    Publication number: 20150372398
    Abstract: The invention relates to a method and apparatus for generating and/or receiving electromagnetic beams with variable orbital angular momentum (OAM) states. The antenna array comprises antenna elements adapted to generate or receive electromagnetic beams with variable OAM. The antenna elements are arranged uniformly in an array plane of the antenna array along a circle. Input signal vectors of input data streams are multiplied with a beam-forming matrix to calculate transmit signal vectors applied to the antenna elements to generate the electromagnetic beams with variable OAM states. Reception signal vectors provided by antenna elements in response to incident electromagnetic beams with variable OAM states are multiplied with the beam-forming matrix to calculate output signal vectors of output data streams. The antenna array is supplemented by a collimating element.
