Open positions for Ph.D. and M.S. students for the project HAF: Underwater Robotics Sensor Networks with Multi-Mode Devices and Remote Power Charging Capabilities

Application Guidelines

Position 1

Acoustic Ultra-Massive MIMO (WP1) and Multi-robot Co-operative Ultra-Massive MIMO (WP3)

The person in position 1 will mainly work on WP1 and WP3. The aim of WP1 is to develop an ultra-massive MIMO array of reconfigurable piezoelectric disks that constitutes the TX or RX end of an acoustic ultra-massive MIMO link. Hundreds of reconfigurable piezoelectric disks are placed on one substrate to form a 2D array. Each of the piezoelectric disks is connected to a phase control circuit so that the phase of the transmitting or receiving signals at each unit can be fully controlled. Focus will be put on the following three tasks, Reconfigurable Piezoelectric Disk Modelling and Optimization, Piezoelectric Disk Array Modelling and Impact Factor Analysis and Underwater Ultra-Massive Acoustic MIMO Channel Characterization. In WP3, novel swarm communication paradigms to maximize the co-operative communication gain will be developed. Two novel underwater co-operative MIMO paradigms are proposed, co-operative massive magnetic MIMO and M2I-assisted co-operative ultra-massive acoustic MIMO. Focus will be put on the following two tasks, Co-operative massive magnetic MIMO optimization and M2I-assisted co-operative ultra-massive acoustic MIMO system optimization.

Specific requirements for Position 1:

  • MSc degree or equivalent in electrical or computer engineering or other related area
  • Experience or good knowledge of MIMO techniques
  • Interest in numerical modelling of underwater acoustics
  • Interest in practical design, building and testing of systems

Position 2

High-Performance Magnetic MIMO (WP2) and Autonomous Underwater Power Delivery (WP4)

The proposed research for this position is High-Gain Magnetic MIMO with Active Metamaterial. To mitigate metamaterial loss and enable reconfigurable transmission frequency, the proposition is to investigate the active metamaterial-enhanced magnetic MIMO technique. Recently, active elements have been introduced to metamaterial to overcome its loss, broaden its bandwidth, and, more importantly, make it reconfigurable. Emphasis is placed on two tasks in WP2, Active metamaterial-enhanced magnetic MIMO antenna prototyping and Stable Transceiver Design. In WP4 an underwater wireless charging system will be developed. This will be enabled by the novel M2I-based underwater charging technology. This technology promises high-efficiency power transfer among mobile robots in a lossy water medium. Emphasis will be placed on two tasks, High-efficiency Mobile Underwater M2I Charging and Underwater Charging Station Network.

Specific requirements for Position 2:

  • MSc degree or equivalent in electrical or computer engineering or other related area
  • Experience or good knowledge of MIMO techniques
  • Interest in numerical modelling of underwater electro-magnetic and notably magnetic induction communications
  • Interest in practical building and testing of systems
