Localization Based on MIMO Backscattering from Retro-Directive Antenna Arrays
In this paper, we propose the exploitation of backscattering from retro-directive antenna arrays (RAAs) to address these imperatives.
Holographic MIMO Communications exploiting the Orbital Angular Momentum
This study delves into the potential of harnessing the orbital angular momentum (OAM) property of electromagnetic waves in near-field and line-of-sight scenarios by utilizing large intelligent surfaces, in the context of holographic multiple-input multiple-output (MIMO) communications.
Grant-free Random Access with Self-conjugating Metasurfaces
This is done in a blind way without the need for RF/ADC chains at the UE side as well as without explicit channel estimation and time-consuming beam alignment schemes.
Communication Modes with Large Intelligent Surfaces in the Near Field
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.
