“…by a human stepping into the path. Ray-tracing simulations have shown that the coverage achieved including once and twice reflected transmission paths critically depends on the reflectivity of the walls [24][25][26]. Koch and coworkers [27] proposed to use flexible dielectric plastic mirrors to enhance the reflectivity of the walls.…”

The increasing demand of unoccupied and unregulated bandwidth for wireless communication systems will inevitably lead to the extension of operation frequencies toward the lower THz frequency range. Higher carrier frequencies will allow for fast transmission of huge amounts of data as needed for new emerging applications. Despite the tremendous hurdles that have to be overcome with regard to sources and detectors, circuit and antenna technology and system architecture to realize ultrafast data transmission in a scenario with extensive transmission loss, a new area of research is beginning to form. In this article we give an overview of emerging technologies and system research that might lead to ubiquitous THz communication systems in the future.

“…1), the possibility of specular non-line-of-sight (NLOS) link pathways has been less well investigated. The idea of engineering specialized reflectors to facilitate this sort of specular NLOS link has been discussed, [59][60][61] and a few examples of NLOS links have been modeled 62 and demonstrated. 63 The impact of surface roughness has also been considered, 54,57 as it could play an important role in degrading the energy transfer through a specular reflection.…”

One of the most exciting future applications of terahertz technology is in the area of wireless communications. As 5G systems incorporating a standard for millimeter-wave wireless links approach commercial roll-out, it is becoming clear that even this new infrastructure will not be sufficient to keep pace with the rapidly increasing global demand for bandwidth. One favorable solution that is attracting increasing attention for subsequent generations of wireless technology is to use higher frequencies, above 100 GHz. The implementation of such links will require significant advances in hardware, algorithms, and architecture. Although numerous research groups are exploring aspects of this challenging problem, many basic questions remain unaddressed. Here, we present an experimental effort to characterize THz wireless links in both indoor and outdoor environments. We report measurements at 100, 200, 300, and 400 GHz, using a link with a data rate of 1 Gbit/s. We demonstrate both line-of-sight and non-line-of-sight (specular reflection) links off of interior building walls. This work represents a first step to establish the feasibility of using THz carrier waves for data transmission in diverse situations and environments.

“…The path loss model for mmwave was studied by comparing the numerical results from Remcom XGTD and measured data in [8], which indicated the path loss model for on-body communication at 94 GHz was closely related to the body shape and garments. At the same time, several papers on THz indoor communications have been published [9], [10]. In addition, the optical parameters of human tissues up to 2.5 THz have been empirically characterized in [11], [12] following the discussion of the possibility of applying EM waves in nano-networks [13].…”

Abstract-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, the proposed model paves the way to the further studies considering more body structures and tissue properties.
