“…PLD was used to assess the local power loss per unit volume in the skin substructures (PLD = 1 2 σ e |E | 2 where σ e = σ s + ω ). The maximum electric field (E max ) and maximum power loss density (PLD max ) represent the highest values of E and PLD in the skin appendages.…”

“…In recent years, the prevalence of smartphones along with their data-intensive applications have spurred a phenomenal growth of mobile data traffic. According to the International Telecommunication Union (ITU), the exponential surge of mobile data traffic will reach 5 zettabyte/month by 2030 [1] whilst the number of devices connected to internet worldwide will exceed 75.4 billion by 2025 [2]. Evidently, the conventional microwave spectrum cannot serve this booming demand for higher data rates.…”

“…In particular, unlicensed allocations have been made in V-band for the development of 5G [3] and next generation Wi-Fi standard (e.g., WiGig) [4]. The mmWave spectrum is also critical for highly anticipated delay sensitive and high-speed communications such as virtual and augmented reality, IoT, autonomous vehicles, smart wearables, real-time telemedicine, remote surgery, and smart factory [2], [5], [6].…”

The purpose of this work is to evaluate local power and electric field distributions inside high-resolution 3D anatomical CAD models of cutaneous appendages at 60 GHz upcoming for 5G/6G. The microscale resolution models of cutaneous nerves, lymphatics, pilosebaceous unit, microvasculature, eccrine sweat glands, Meissner corpuscle and Pacinian corpuscle were designed based on morphometric data and microscopic images. The Maxwell's and Hanai's mixture equations were employed to retrieve the complex permittivity of cutaneous appendages based on their free water content. The cutaneous appendages were exposed to a uniform plane wave. The finite element method was used to compute the power loss density (PLD) and internal electric field (E). The results indicate that the maximal PLD in cutaneous appendages occurred for E polarized along their longest dimension. Higher peak PLD was observed in high water content cutaneous appendages such as acrosyringium (45%), epidermal axon (37.9%), Pacinian corpuscle (32.5%), blood capillary (30.6%), lymph capillary (20%) and arrector pili muscle (13.5%) compared to the surrounding skin. Higher E was detected in low water content hair with the peak E 45.1% greater than in surrounding skin. The interfaces of the cutaneous appendages also manifested a boost (23.8%-60.9%) in PLD compared to the surrounding skin. Detailed physical interpretation of observed phenomena is provided in the article. These results provide an insight into microscale power deposition in skin at frequencies upcoming for wireless communications.

“…Also, in the cognitive Industrial IoT system [36], multiple sensing stations worked together and transmitted the sensing information to the data center by non-orthogonal communication to improve the data transmission efficiency. Besides, the JCS NOMA network framework was proposed recently in [37], in which the transmitted and received beamforming were designed for minimizing the computational error and maximizing weighted sum rate. Indeed, [34]- [37] provided embryonic forms for the development of JCS NOMA systems, whereas the JCS cooperative scheme was not considered, and the performance analysis of the system was lacked as well.…”

To mitigate the radar and communication frequency overlapping caused by massive devices access, we propose a novel joint communication and sensing (JCS) system in this paper, where a micro base station (MiBS) can realize target sensing and cooperative communication simultaneously. Concretely, the MiBS, as the sensing equipment, can also serve as a full-duplex (FD) decode-and-forward (DF) relay to assist the end-to-end communication. To further improve the spectrum utilization, non-orthogonal multiple access (NOMA) is adopted such that the communication between the macro base station (MaBS) and the Internet-of-Things (IoT) devices. To facilitate the performance evaluation, the exact and asymptotic outage probabilities, ergodic rates, sensing probability of the system are characterized. Subsequently, two optimal power allocation (OPA) problems of maximizing the received signal-tointerference-plus-noise ratio of sensing signal and maximizing the sum rate for communication are designed that are solved by means of the Lagrangian method and function monotonicity. The simulation results demonstrate that: 1) the proposed JCS NOMA system can accomplish both communication
