Movable Antennas and Holographic Surfaces in Wireless Communication

The field of wireless communication is moving towards the adoption of movable antennas and holographic surfaces to enhance security, improve beamforming, and increase spectral efficiency. Researchers are exploring the potential of movable antenna arrays to adjust channel correlations between legitimate users, eavesdroppers, and jammers, thereby enhancing physical layer security. Holographic surfaces are being investigated for their ability to achieve significant beamforming gains and improve both communication and sensing performance in integrated sensing and communication systems. The consideration of mutual coupling effects in holographic beamforming is becoming increasingly important to suppress sidelobes and enhance system performance. Furthermore, the development of low-complexity CSI acquisition algorithms and hybrid beamforming techniques is crucial for the practical implementation of these systems. Noteworthy papers in this area include: Movable Antenna Empowered Secure Near-Field MIMO Communications, which proposes an alternating optimization-based algorithm to maximize secrecy rate in near-field MIMO systems. Holographic Beamforming for Integrated Sensing and Communication with Mutual Coupling Effects, which develops an efficient mutual coupling aware holographic beamforming algorithm to suppress sidelobes and enhance ISAC performance.
