“…Meanwhile, in [27], a propagation model for intra-body nano-scale communications was provided. Likewise, in [28], a path-loss model, which quantifies the total absorption loss assuming that air, natural gas and/or water are the components of the propagation medium, was discussed, whereas, in [29], a multi-ray THz propagation model was presented.…”

This paper is focused on providing the analytical framework for the quantification and evaluation of the joint effect of misalignment fading and hardware imperfections in the presence of multipath fading at terahertz (THz) wireless fiber extenders. In this context, we present the appropriate system model that incorporates the different operation, design, and environmental parameters. In more detail, it takes into account the transceivers antenna gains, the operation frequency, the distance between the transmitter (TX) and the receiver (RX), the environmental conditions, i.e., temperature, humidity, and pressure, the spatial jitter between the TX and RX antennas that results to antennas misalignment, the level of transceivers' hardware imperfections, and the stochastic characteristics of the wireless channel. Based on this model, we analyze and quantify the joint impact of misalignment and multipath fading by providing novel closedform expressions for the probability and cumulative density functions of the composite channel. Moreover, we derive exact closed-form expressions for the outage probability for both cases of ideal and non-ideal radio frequency (RF) front-end. In addition, in order to quantify the detrimental effect of misalignment fading, we analytically obtain the outage probability in the absence of misalignment cases for both cases of ideal and non-ideal RF front-end. In addition, we extract the novel closed-form expressions for the ergodic capacity for the case of the ideal RF front-end and tight upper bounds for both the cases of ideal and non-ideal RF front-end. Finally, an insightful ergodic capacity ceiling for the non-ideal RF front-end case is provided.

This paper presents the theoretical framework for the performance evaluation of terahertz (THz) wireless fiber extender in the presence of misalignment and multipath fading. In more detail, after providing the appropriate system model that incorporates the different operation, design, and environmental parameters, such as the operation frequency, transceivers antenna gains, the level of misalignment as well as the stochastic behavior of the channel, we extract novel closed-form expressions for the ergodic capacity. These expressions are expected to be used as useful tools for the analysis and design of such systems. Moreover, several insightful scenarios are simulated. Their results highlight the importance of taking into account the impact of misalignment fading when analyzing the performance of the THz wireless fiber extender.

“…At THz range when electromagnetic waves propagate, they vibrate molecules and kinetic energy formed. Absorption coefficient is the absorb energy that is measured from the vibrate molecules [14,15]. In this paper Radiative transfer theory [16] and HIgh resolution TRANsmission molecular absorption database (HITRAN) have been used [17].…”

In this paper, we electromagnetically analyzed the wireless sensor nodes for natural gas transport system from the recovery process to our apartments. In light of the problems of poor localization accuracy, low recognition efficiency and high false rates in traditional pipeline security and detection technology, this paper suggests a type of new electromagnetic modeling for the natural gas pipeline and tank system. This paper describes the effect of natural gas at different temperature and pressure levels on the propagation characteristics of electromagnetic waves at Terahertz Band frequencies. Based on the calculated absorption and path losses, the channel capacity and SNR are studied to give an insight of future Terahertz communication networks. Results show that characteristics of electromagnetic waves propagation affected by both the temperature and pressure. As a result, in the paper we come to the conclusion that frequency bands for optimum performance should be determined by reviewing the absorption coefficient.
