“…The explosive development of mobile devices and multimedia applications appeals for powerful wireless communication techniques to provide larger bandwidths and higher throughput. Some communication technologies are employed to increase the capacity of wireless communications, e.g., TeraHertz [1] and millimeter-Wave communications [2], as well as extreme multiple-input multiple-output (MIMO) [3], [4]. However, the massive data traffic and high reliability of wireless communications still pose serious challenges to algorithmic and hardware designs.…”

This paper investigates the utilization of triple polarization (TP) for multi-user (MU) holographic multiple-input multi-output surface (HMIMOS) wireless communication systems, targeting at capacity boosting and diversity exploitation without enlarging the antenna array sizes. We specifically consider that both the transmitter and receiver are both equipped with an HMIMOS consisting of compact sub-wavelength TP patch antennas within near-field (NF) regime. To characterize TP MU-HMIMOS L. Wei and C. Yuen are with the Engineering Product Development (EPD) Pillar,

“…Among the recent advances in the field of wireless communications, reconfigurable intelligent surfaces (RISs) are emerging as new network entities that help connect remote devices, especially in an indoor environment with many blockages (e.g., walls, equipment and tables) [13]. An RIS contains multiple reconfigurable reflecting elements that can control the diffusion of an incident wave and create artificial communication channels between a pair of transceivers [14], [15]. Due to the novelty of RISs, their role in supporting Industry 4.0 remains an open question.…”

“…In recent years, the demand for ubiquitous wireless communications is growing due to the explosive development of mobile devices and multimedia applications [1]. To satisfy the expanding demands, the exploitation of the ultimate limits of communication techniques is concerned, and new technologies to provide higher bandwidth and energy efficiency also attract great interest, e.g., TeraHertz (THz) [2] and millimeter-Wave (mmWave) communications [3], as well as extreme Multiple-Input Multiple-Output (MIMO) catering for massive users and throughput [4], [5]. However, more profound requirements for data rate and massive connections are needed for 6th Generation (6G) wireless communications.…”

“…One of the main challenges is multi-user channel modeling due to the spatially continuous aperture realized by holographic patch antennas [5]. The traditional channel models are not applicable for various reasons, e.g., the coupling between antennas, their massive numbers, and the surface-to-surface transmission.…”

The multi-user Holographic Multiple-Input and Multiple-Output Surface (MU-HMIMOS) paradigm, which is capable of realizing large continuous apertures with minimal power consumption and of shaping radio wave propagation at will, has been recently considered as an energy-efficient solution for future wireless networks. The tractable channel modeling of MU-HMIMOS signal propagation is one of the most critical challenges, mainly due to the coupling effect induced by the excessively large number of closely spaced patch antennas. In this paper, we focus on this challenge for downlink communications and model the electromagnetic channel in the wavenumber domain using the Fourier plane wave representation. Based on the proposed model, we devise a Zero-Forcing (ZF) precoding scheme, capitalizing on the sampled channel variance that depends on the number and spacing of the HMIMOS patch antennas, and perform a spectral efficiency analysis. Our simulation results showcase that the more patch antennas and the larger their spacing is, the performance of the considered MU-HMIMOS system improves. In addition, it is demonstrated that our theoretical performance expressions approximate sufficiently well the simulated spectral efficiency, even for the highly correlated cases, thus verifying the effectiveness and robustness of the presented analytical framework.
