The field of near-field communications and physical layer security is experiencing significant growth, with a focus on developing innovative solutions to enhance security and communication rates. Recent research has explored the use of rate-splitting multiple access (RSMA) and artificial noise to improve secrecy performance in near-field communications. Additionally, the design of hybrid beamfocusing and precoding schemes has been investigated to mitigate energy leakage and interference. The integration of movable antenna technology and fluid antenna systems has also shown promise in enhancing sensing capabilities and physical layer security. Noteworthy papers in this area include: ORBGRAND Is Exactly Capacity-achieving via Rank Companding, which established that ORBGRAND achieves the symmetric capacity of general binary-input memoryless channels. Robust Precoding Designs of RSMA for Multiuser MIMO Systems, which proposed a novel robust precoding design for RSMA that can handle imperfect channel state information. Artificial Noise Aided Physical Layer Security for Near-Field MIMO with Fluid Antenna Systems, which presented an artificial-noise-aided physical layer security scheme for near-field fluid-antenna multiple-input multiple-output systems.
