“…THz science and technology [1] are continuously growing since the early report on THz wave emission [2]. Applications have been demonstrated in imaging [3] with optical component developments [4], spectroscopy for mesoscopic structures [5], coherent measurements of intense THz wave [6], gas-detection in Fabry-Pérot cavity [7], tunable/compact laser [8], sensing for medical uses [9], and next generation 6G wireless communication [10]. Recent progresses include studies under scanning tunneling microscopy [11][12][13] with nanoscale spatial resolution.…”

Giant Enhancement of THz Wave Emission under Double-Pulse Excitation of Thin Water Flow

et al. 2020

Simultaneous measurements of THz wave and hard X-ray emission from thin and flat water flow when irradiated by double femtosecond laser pulses (800 nm, 35 fs, transform-limited, 0.5 kHz, delay times up to 15 ns) were carried out at the transmission and the reflection sides of the flow with THz time-domain spectroscopy and Geiger counters. THz wave emission spectra show their dynamic peak-shifts toward the low frequency with the highest intensity enhancements more than 1.5 × 10 3 times in |E| 2 at the delay time of 4.7 ns between the two pulses, while X-ray intensity enhancements are limited to about 20 times at 0 ns under the same experimental conditions. The mechanisms for the spectral changes and the intensity enhancements in THz wave emission are discussed from the viewpoint of laser ablation on the water flow induced by the pre-pulse irradiation.

“…For meeting the exceptionally high throughput demands of future networks, one venue can be the exploration of mmWave, sub-teraHz, and teraHz bands. Moreover, communication in the optical spectrum (visible light) may also attract various LoS and indoor communication applications [14]. d) Inter-portability and Congestion in Heterogeneous Networks: The 5G networks will operate in the coexistence of its predecessors (1G to 4G).…”

“…In this direction, this paper proposes the development of a unified data hub with layered structured privacy and security along with blockchain and encrypted off-chain based ownership/royalty deployment cost, ii) the explosion of connected devices caused by the advent of mMTCs may very rapidly lead towards reaching the network capacity limit, iii) the rate and volume of the data generated in hyper massively connected 5G networks may need new data analytic innovations, and iv) the privacy and security provisions in massively connected networks -to name a few. The telecommunication engineers, industries, and researchers from around the globe have also already initiated the speculative propositions for network requirements and candidate technologies for beyond 5G (B5G) networks, see e.g., [10][11][12][13][14].…”

The Potential Short- and Long-Term Disruptions and Transformative Impacts of 5G and Beyond Wireless Networks: Lessons Learnt From the Development of a 5G Testbed Environment

et al. 2020

The capacity and coverage requirements for 5G and beyond wireless connectivity will be significantly different from the predecessor networks. To meet these requirements, the anticipated deployment cost in the UK is predicted to be in between £30bn-£50bn, whereas the current annual capital expenditure (CapEX) of the mobile network operators (MNOs) is £2.5bn. This prospect has vastly impacted and has become one of the major delaying factors for building the 5G physical infrastructure, whereas other areas of 5G developments are progressing at their speeds. Due to the expensive and complicated nature of the physical network infrastructure and spectrum, the second-tier operators, widely known as mobile virtual network operators (MVNO), are entirely dependent on the MNOs. In this paper, an extensive study is conducted to explore the possibilities of reducing the 5G deployment cost and developing business models. This study suggests that the use of existing public infrastructure (e.g., streetlights, telephone poles, etc.) has a great potential to contribute to a reduction of about 40% to 60% anticipated cost for the 5G network. This paper also reviews the recent Ofcom initiatives to release location-based licenses of the 5G-compatible radio spectrum at a nominal cost. Our study suggests that simplification of infrastructure and spectrum will encourage the exponential growth of scenario-specific cellular networks and will potentially disrupt the current business models of telecommunication business stakeholders -specifically MNOs and TowerCos. These scenario-specific networks are expected to be: a) private networks, b) community networks, and c) microoperators. Furthermore, due to the feasibility of dense device connectivity with 5G, the resolution of traditional and nontraditional data availability will increase significantly. This will encourage extensive data harvesting as a business opportunity and function within small and medium-sized enterprises (SMEs) as well as within large social networks. Consequently, the rise of new infrastructures and spectrum stakeholders is anticipated. This will fuel the development of a 5G data exchange ecosystem where data transactions are deemed to be high-value business commodities. The privacy and security of such data, as well as definitions of the associated revenue models and ownership, are challenging areas -and these have yet to emerge and mature fully. In this direction, this paper proposes the development of a unified data hub with layered structured privacy and security along with blockchain and encrypted off-chain based ownership/royalty

“…Electromagnetic (EM) characterization of engineered artificial materials such as bio-, nanomaterials and composite materials is very important for several reasons. One of these reasons is future proliferation of 5G communication networks [1] exposing urban population into the EM radiation of wide spectral range, therefore it is critically important to understand how new materials EM response can be utilized in electronic and communication devices and also ensure the EM compatibility of biomaterials used in human body. Future smart fabrication, construction engineering, aerospace and automotive industry would also benefit from online in-situ characterization of composite materials [2] used in structures and constructions.…”

A novel method for electromagnetic (EM) characterization of engineered artificial materials such as bio-, nanomaterials and composite materials is proposed and experimentally evaluated in this paper. The method is based on resonance transmission properties of capacitively loaded apertures in conductive screens. The advantage of this new method over the existing techniques (free space, loaded waveguide, microstrip and coplanar waveguide resonators, coaxial probe, etc) is three-fold: i) resonance EM field enhancement inside the loaded aperture leads to very high sensitivity and therefore accuracy of EM parameters de-embedding; ii) only small thin samples of material-under test are required (with sample area substantially smaller than squared wavelength of radiation, ~0.01 λ 2 ); iii) the method is easily scalable over the frequency and wavelength and based on relatively simple permittivity and permeability de-embedding procedure. The experimental setup in the microwave S-band (2-3GHz) is based on two dipole antennas, capacitive aperture in the conductive screen, unloaded and loaded with material under test, and vector network analyser (VNA) for signal generation and data acquisition. Analytical de-embedding procedure is developed and applied to the characterization of carbon nanotube (CNT) material microwave absorption. It is demonstrated that the method offers very high accuracy in material characterization based on minimal material samples.
