A Breakthrough in Antenna Technology: Manipulating Electromagnetic Waves

In an unprecedented development, a research team led by Professor Chan Chi-hou, Chair Professor of Electronic Engineering at City University of Hong Kong (CityU), has achieved a significant advance in antenna technology. Through software control, the team has made it possible to manipulate all five fundamental properties of electromagnetic waves. This breakthrough holds immense potential for various applications in 6G wireless communication systems, including real-time imaging, high-security information systems, and wireless power transfer.

The universal metasurface antenna, developed by Professor Chan’s team, allows for the independent and simultaneous manipulation of amplitude, phase, frequency, polarization, and direction of electromagnetic radiation. Physicists and engineers have long pursued the development of a universal component capable of manipulating all these fundamental wave properties. This achievement represents a significant milestone in the field, opening up new possibilities for advanced waveform manipulation and enhanced security features in integrating sensing and communication systems.

The applications of the universal metasurface antenna are far-reaching. In 6G systems, it can contribute to the development of next-generation, large-capacity, high-security information systems. Its ability to manipulate waves in real-time imaging makes it invaluable for a range of imaging applications. Additionally, the antenna’s direction modulation properties enhance privacy and security, making it an ideal choice for eavesdropper-proof communications.

The achievement of this breakthrough was made possible through a collaboration between CityU and Southeast University. Professor Chan emphasizes that the partnership between the two institutions was vital in tackling complex research challenges and achieving groundbreaking results. By bringing together diverse perspectives and knowledge, the joint expertise and resources from both universities facilitated the successful development of the universal metasurface antenna.
