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...
In this paper, the channel model is proposed to compute the path loss, delay and noise at THz band of interest (0.5 THz ∼ 1.5 THz). The results shows that THz band channel is strongly dependent on both the type of the medium and the distance while the concentration of water have a lot of influence because it not only causes attenuation to the THz wave but also introduces non-white noise. Therefore,...

This letter investigates nanoscale wireless communications in human tissues. Starting from propagation models, validated through real experiments, channel capacity and transmission ranges are derived for different physical transmission settings. Results highlight the challenges characterizing the communication in such a medium, thus, paving the way to novel research activities devoted to the design...
With the growth of the demand of smaller and smaller implantable devices, THz technologies becomes appealing for potential applications in Body Area Networks at nano-scale. As an essential part for understanding the in-body propagation at THz frequency numerical investigations are presented in this paper to simulate the absorption path loss of fat at THz frequency. The results of the proposed analysis...
