2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS)
Realization of a non-interfering and equally strong multi-channel MIMO communication in the near-field regime is presented. This is achieved by introducing decoupling and matching networks that optimize the transmitted power. A demonstration of such
