Revolutionary Breakthrough in Antenna Technology: Manipulating the Five Fundamental Properties of Electromagnetic Waves

Researchers led by Professor Chan Chi-hou, an esteemed Chair Professor of Electronic Engineering at City University of Hong Kong (CityU), have achieved a significant milestone in antenna technology. Through software control, they have successfully manipulated all five fundamental properties of electromagnetic waves. This groundbreaking development has paved the way for the creation of a universal metasurface antenna capable of independently and simultaneously controlling amplitude, phase, frequency, polarization, and direction of electromagnetic radiation.

As the world ventures into the realm of 6G wireless communication systems, the universal metasurface antenna holds immense potential for various applications in this domain. Its advanced waveform manipulation capabilities and enhanced security features are crucial for integrating sensing and communications, providing an ideal solution for next-generation, large-capacity, high-security information systems. Moreover, the antenna’s inherent direction modulation properties offer an added layer of privacy and security, making it an excellent candidate for eavesdropper-proof communications.

The research team’s findings were published in the prestigious scientific journal Nature Communications. Co-first author Professor Wu Gengbo, from the Department of Electrical Engineering and a member of the State Key Laboratory of Terahertz and Millimeter Waves (SKLTMW), explained that the universal metasurface antenna can manipulate information by directly generating the modulated waveform in free space. This breakthrough has the potential to revolutionize information transmission with its low cost, high integration, and low power consumption. The possibilities are indeed exciting.

This achievement was made possible through collaboration between CityU and Southeast University. Professor Chan emphasized the significance of this partnership, stating that it was instrumental in tackling complex research challenges and ultimately achieving groundbreaking results. By combining their expertise and resources, both institutions played an integral role in the successful development of the universal metasurface antenna. This collaboration allowed for the convergence of diverse perspectives and knowledge, facilitating the birth of this revolutionary technology.

The invention of the universal metasurface antenna introduces new features that have the potential to transform the landscape of integrating sensing and communications. With this remarkable breakthrough, exciting possibilities are on the horizon. The antenna’s ability to manipulate all fundamental wave properties opens up avenues for real-time imaging, wireless power transfer, and a multitude of applications we have yet to explore fully.

Professor Chan expressed his enthusiasm for this achievement, highlighting the importance of developing a universal component capable of manipulating all the fundamental wave properties. This breakthrough represents the Holy Grail for physicists and engineers alike. By conquering this milestone, the research team has pushed the boundaries of what was once deemed impossible, blazing a trail for future innovations and advances in antenna technology.

The groundbreaking research led by Professor Chan and his team at City University of Hong Kong has undeniably revolutionized antenna technology. The creation of the universal metasurface antenna, with its unprecedented ability to manipulate all five fundamental properties of electromagnetic waves, holds immense promise for the future. As we venture into the era of 6G wireless communication systems, this breakthrough will undoubtedly shape the way we approach information transmission, privacy, security, and a myriad of other applications we have yet to discover. With its low cost, high integration, and low power consumption, the universal metasurface antenna is not only an impressive scientific achievement but also a key turning point in our technological journey.
