Recently, a groundbreaking achievement has emerged from Professor Li Long's research team at Xidian University in the realm of Reconfigurable Intelligent Surfaces (RIS). Their significant findings have been published in the prestigious National Science Review. The study introduces an electromagnetic multi-dimensional fused amplitude-scattering reconfigurable intelligent surface, laying down a theoretical foundation and a unified physical framework for integrated management of radiation and scattering. This framework encompasses the multi-dimensional attributes of electromagnetic waves, including phase, polarization, amplitude, waveform, frequency, and time, thereby facilitating tailored design for both information and energy transmission.
Furthermore, the team has developed a comprehensive theory and physical platform for the integrated management of wireless energy and information, dubbed the 'communication-sensing-decision-making-energy supply' model. This innovative approach seamlessly integrates communication, sensing, and energy transmission into a single hardware system, enabling multifunctional decision-making capabilities without the necessity for additional sensors.
The implications of these findings are profound, offering a fresh technological paradigm for 6G communication networks, extending the operational endurance of intelligent unmanned aerial vehicles, and facilitating the intelligent interconnection of all entities within wireless sensor networks. This advancement promises substantial reductions in both hardware costs and system power consumption, marking a significant leap forward in the field.
