“…Conceptually, in a long-range transmission, the transmitter coil can be regarded as a magnetic dipole loop antenna driven by currents. Consider a squared coil transmitter with side length l t and coil turns N t ; the magnetic field intensity B produced by a current I with frequency f flowing through the coil can be calculated by adding together a contribution generated by four segments of the coil [5,27]. Considering a signal transmission along the normal direction of the coil in a non-conductive environment, the magnetic field intensity B at a distance d can be derived as:…”

“…Magnetic induction (MI) communication technology, which has been proposed and developed in recent years, is now considered as a reliable and low-power-consumption substitute for traditional EM communication in radio frequency (RF) challenging environments, and has attracted great interest from many research communities [2][3][4][5][6][7] . This technology employs a magnetic field as the carrier instead of traditional EM waves for data transmission.…”

The communication range of magnetic-induction (MI) technology in extreme environments such as underwater or underground is limited by the dipole-like attenuation behavior of the magnetic field as well as the eddy current induced loss in conductive media, and therefore a highly sensitive receiver is generally required. In this work, we propose the use of a highly sensitive superconducting quantum interference device (SQUID) in MI communication and try to provide a comprehensive investigation on developing a SQUID-based receiver for practical MI applications. A portable receiver scheme integrating a SQUID sensor and a coil-based flux transformer was proposed. The high sensitivity and long-range communication capability of the proposed receiver was experimentally demonstrated by spectroscopic measurements and reception experiments on a receiver prototype. Based on the experimental demonstrations, the sensitivity optimization of the proposed scheme was further investigated by simulation studies, which suggest that a communication distance exceeding 100 m and a channel capacity of ∼20 kb/s in underwater environment could be achieved based upon the optimization of the developed prototype. The results presented in this work have highlighted the potential of deploying SQUID sensors for long-range MI applications in extreme environments.

Design of AUVs based on 3D coils positioning and distributed base station control for nuclear spent fuel pools

et al. 2023

An underwater magnetic induction positioning and communication system and an energy-efficient distributed control algorithm for underwater base stations are proposed in this paper. The positioning and communication system consists of a number of base stations and an Autonomous Underwater Vehicle (AUV) equipped with three-axis source coils respectively. The AUV receives this signal and based on its amplitude and phase information is able to locate the AUV and communicate with the base station. Due to the short positioning distance of magnetic induction positioning technology, a large number of base stations need to be installed underwater, which puts high demands on the control of the base stations. In this paper, an energy-efficient distributed control algorithm for underwater base stations is proposed to enable the AUV to meet the operational requirements while minimizing the total energy consumption of the base station. According to the simulation results, the design solves the problem that traditional underwater positioning and communication equipment cannot work stably for long periods of time in a high radiated environment, with a positioning error of no more than 10 cm within a preset operating range, and the algorithm proposed in this paper is able to reduce energy wastage by about 20%.
