论文摘要
全息通信旨在用前所未有的灵活性操纵电磁场或感应天线的电磁场。当在高频（例如，毫米波或Terahertz）下使用大型天线时，这是特别感兴趣的，其工作条件可能很容易落在壁垒的传播区域（辐射近场）中，那里经典的平面波传播假设不再有效。本文分析了涉及大型智能表面的最佳沟通，例如使用超材料作为可能的全息沟通技术实现。结果表明，必须修改传统的繁殖模型，并且在利用菲涅耳区域的球形波传播具有较大表面时，例如，就正交通信渠道的数量而言，开放了新的机会。
Holographic communication is intended as an holistic way to manipulate with unprecedented flexibility the electromagnetic field generated or sensed by an antenna. This is of particular interest when using large antennas at high frequency (e.g., the millimeter wave or terahertz), whose operating condition may easily fall in the Fresnel propagation region (radiating near-field), where the classical plane wave propagation assumption is no longer valid. This paper analyzes the optimal communication involving large intelligent surfaces, realized for example with metamaterials as possible enabling technology for holographic communication. It is shown that traditional propagation models must be revised and that, when exploiting spherical wave propagation in the Fresnel region with large surfaces, new opportunities are opened, for example, in terms of the number of orthogonal communication channels.
