收发器和天线的小型化推动了片上无线网络（WNoC）的发展，在这种网络中，片上规模的通信被用于提升多核/多芯片架构的计算性能。尽管WNoC范式的潜在优势已得到深入研究，但由于缺乏对片上规模及全频段无线信道的恰当特性描述等原因，其实用性仍不明确。本文对片上规模通信的电波传播与信道建模的最新进展进行了综述。首先，回顾了WNoC的特点，包括设计驱动因素、架构、环境以及片上电磁特性。在简要介绍了表征片上规模电波传播的不同方法后，对毫米波（mmWave）、太赫兹（THz）和光频等不同频段的相关研究进行了全面讨论。最后，探讨了WNoC信道特性表征方面的主要挑战及应对这些挑战的潜在解决方案，为实用型WNoC的基础研究提供了路线图。
The miniaturization of transceivers and antennas is enabling the development of Wireless Networks-on-Chip (WNoC), in which chip-scale communication is utilized to increase the computing performance of multi-core/multi-chip architectures. Although the potential benefits of the WNoC paradigm have been studied in depth, its practicality remains unclear due to the lack of a proper characterization of the wireless channel at the chip scale and across the spectrum, among others. In this paper, the state of the art in wave propagation and channel modeling for chip-scale communication is surveyed. First, the peculiarities of WNoC, including the design drivers, architecture, environment, and on-chip electromagnetics are reviewed. After a brief description of the different methods to characterize wave propagation at chip-scales, a comprehensive discussion covering the different works at millimeter-wave (mmWave), Terahertz (THz) and optical frequencies is provided. Finally, the major challenges in the characterization of the WNoC channel and potential solutions to address them are discussed, providing a roadmap for the foundations of practical WNoCs.
