Communication Modes With Large Intelligent Surfaces in the Near Field [PDF]
IEEE Access, 2021 This paper proposes a practical method for the definition of communication modes when antennas operate in the near-field region, by realizing ad-hoc beams exploiting the focusing capability of large antennas. The beamspace modeling proposed to define the communication modes is then exploited to derive expressions for their number (i.e., the degrees of ...

A Communication Model for Large Intelligent Surfaces [PDF]
2020 IEEE International Conference on Communications Workshops (ICC Workshops), 2020 The purpose of this paper is to introduce a communication model for Large Intelligent Surfaces (LIS). A LIS is modelled as a collection of tiny closely spaced antenna elements. Due to the proximity of the elements, mutual coupling arises. An optimal transmitter design depends on the mutual coupling matrix.
