Description

Recently, there has been a growing demand for wireless devices that are able to collect and retransmit data by means of a wireless channel. Consequently, there is an increasing demand for clean energy sources. They require high efficiency and low maintenance operations. Wireless power transmission (WPT) is a method that generates electricity with electromagnetic (EM) waves.

Different systems have been proposed for practical applications such as charging ubiquitous electronic devices such as mobile phones and laptops, powering pervasive sensors and actuators (e.g., wireless sensor nodes and robots). Current research is focused on fuelling electric vehicles. The solar power satellite (SPS) is not a new concept. In 1968, Peter E. Glaser proposed the idea of solar power stations (SPS). He hypothesized that the power generated in space can be beamed down to the earth using radiofrequency (RF) signals. He gave a theoretical prediction that 10 gigawatts of power can be beamed down by an RF signal of frequency 5.8 gigahertz (GHz). Recently, SPS has gained interest amongst researchers in the field. Innovative techniques are being explored by scientists and engineers worldwide.

The aim of this Special Issue is to provide an overview of the current research on microwave and radiofrequency long-range wireless power transmission techniques. We welcome submissions discussing unconventional radio frequency identification (RFID) systems. We also hope that this Special Issue highlights the latest innovations and helps identify challenges and opportunities. Original research and review articles are welcome.

Potential topics include but are not limited to the following:

  • Rectifying antenna circuits and systems
  • Chipless and powerless RFID systems
  • Long-range RFID systems
  • Powerless modulated scattering techniques (MST)
  • Sensing and wearable powerless RFID systems for biomedical applications
  • Wireless power transmission antennas
  • Powerless Internet of things (IoT)
  • Machine learning assisted wireless power transfer
  • Wireless power for smart grids
  • Transducers for wireless power transfer
