“…The material properties i.e., refractive index and absorption coefficient are calculated using details given in [24]. The total path loss is calculated by converting the measured time domain data to frequency domain by applying fast fourier transform and then averaging it across the band of interest [12], [15] for THz channel inside the skin. The measured sample pathloss results are compared with the modeled pathloss as per eq.…”

“…[12] studied the THz channel model in the air by varying water vapor concentration and also proposed a new physical-layer aware medium access control (MAC) protocol [14]. The characteristics of electromagnetic waves propagating inside human body at terahertz frequencies have been studied in [15], which shows that path loss has a relation with the dielectric loss of human tissues. In [16], the electrical properties (conductivity and permittivity values) of each layer have been investigated depending on the water content of each layer.…”

Thorough studies are performed on the attenuation of electromagnetic waves inside the human skin, while taking into account the frequency of operation, distance between the nano-machines and number of sweat ducts. A novel channel model is presented for communication of nano-machines inside the human skin and its validation is performed by varying the aforementioned parameters with a reasonable accuracy. The statistics of error prediction between simulated and modeled data are: mean (µ) = 0.6 dB and standard deviation (σ) = 0.4 dB, which indicates the high accuracy of prediction model as compared with measurement data from simulation. In addition, the results of proposed channel model are compared with Terahertz Time Domain Spectroscopy based measurement of skin sample and the statistics of error prediction in this case are: µ = 2.10 dB and σ = 6.23 dB, which also validates the accuracy of proposed model. Results in this paper highlight the issues and related challenges while characterizing the communication in such a medium, thus paving the way towards novel research activities devoted to the design and the optimization of advanced applications in the health-care domain.

“…Channel modelling of the THz wave propagating in the atmosphere with a different concentration of the water vapour was first studied in [2,3]. Subsequently, both numerical and analytical EM channel modelling at the THz band for in-body nano-communication was investigated in [4] . In order to quantify the potential of the THz communication, channel capacity is used as an important performance metric and to proceed with realistic and accurate representation of the actual capacity and channel model in the THz band, consideration of channel noise model is necessary.…”

“…For the time being, some studies have been conducted for THz channel noise characterisation [2][3][4]. A noise model for nano-communication channels in the atmosphere was first introduced in [2], approximating the noise temperature as the molecular absorption noise, which is considered as a basis in [5,6].…”

“…A noise model for nano-communication channels in the atmosphere was first introduced in [2], approximating the noise temperature as the molecular absorption noise, which is considered as a basis in [5,6]. Same noise model was applied in [4] as well to characterise the in-vivo nano-communication channel. This noise model only takes into account the radiation energy of the medium and focuses on the transformation of the energy directly into antenna temperature, while ignoring the molecular absorption from the transmitted signal.…”

Abstract-This paper focuses on the modelling of communication channel noise inside human tissues at the THz band (0.1-10THz). A novel model is put forward based on the study of the physical mechanism of the channel noise in the medium, which takes into account both the radiation of the medium and the molecular absorption from the transmitted signal. The derivation and the general concepts of the noise modelling is detailed in the paper. The results show that the channel noise power spectral density at the scale of several micrometres is at acceptable levels and the value tends to decrease with the increase of both distance and frequency. In addition, the channel noise is also related to the composition of the human tissues, with the result of higher channel noise in tissues with higher water concentration. The conclusion drawn from the conducted study and analysis paves the way for more comprehensive characterisation of the electromagnetic channel within in-vivo nano-networks.
