本文提出了有关在太赫兹频率下运行的纳米级网络的分析研究。本文研究了无线体域网 (WBAN) 内简化人体模型的路径损耗和吸收系数。数值结果表明，路径损耗随着距离和频率的增加而增加。研究发现，对于不同的身体部位，在 1mm 距离处，跨 0.1 THz 到 10 THz 的 THz 频段的路径损耗差异约为 40 dB。这是一个可接受的值，特别是在体内纳米通信的背景下。在 1 THz 时，对于不同的身体部位，1 毫米和 1.5 毫米之间的路径损耗范围在 36 dB 和 40 dB 之间。本文获得的结果验证了电磁（EM）通信是体内太赫兹纳米通信建模的有效分析假设。这主要是因为对于毫米级的距离，太赫兹的路径损耗并不是很高。
This paper presents an analytical study concerning nanoscale networks operating at the Terahertz frequency. The paper investigates the path loss and absorption coefficients of a simplified human model within wireless body area networks (WBANs). Numerical results indicated that the path loss rises with increased distance and frequency. It was found that the path loss difference across the THz band ranging between 0.1 THz and 10 THz at a distance of 1mm is around 40 dB, for the various body parts. This is an acceptable value especially in the context of in-vivo nano-communication. At 1 THz, the path loss between 1 mm and 1.5 mm ranges betweenb 36 dB and 40 dB, for the different body parts. The results obtained in this paper verify that electromagnetic (EM) communication is a valid analytical assumption for modeling in-vivo THz nano-communication. This is mainly due to the fact that for distances in the order of millimeters, the path loss at THz is not significantly high.
