Robust Adaptive Beam Tracking for Mobile Millimetre Wave Communications [PDF]
IEEE Transactions on Wireless Communications, 2020 Millimetre wave (mmWave) beam tracking is a challenging task because tracking algorithms are required to provide consistent high accuracy with low probability of loss of track and minimal overhead. To meet these requirements, we propose in this article a

Millimetre-Wave Metamaterial-Based Sensor for Characterisation of Cooking Oils
, 2021 The characterisation of the cooking oils presents a significant challenge due to minor changes in their dielectric behaviour. In this paper, a new metamaterial-based sensor incorporating a split-ring resonator (SRR) with a microstrip transmission line is

Beam-Based Mobility Management in 5G Millimetre Wave V2X Communications: A Survey and Outlook
IEEE Open Journal of Intelligent Transportation Systems, 2021 It is envisaged that 5G can enable many vehicular use cases that require high capacity, ultra-low latency and high reliability. To support this, 5G proposes the use of dense small cells technology as well as and highly directional mmWave systems ...

Propargylimine in the laboratory and in space: millimetre-wave spectroscopy and its first detection in the ISM [PDF]
Astronomy & Astrophysics, 2020 Context. Small imines containing up to three carbon atoms are present in the interstellar medium (ISM). As alkynyl compounds are abundant in this medium, propargylimine (2-propyn-1-imine, HC ≡C−CH =NH) thus represents a promising candidate for a new ...
