Abstract
Meta-lenses, distinguished by their compact size and adaptable manipulation, have attracted considerable interest. Yet, challenges persist for conventional tunable meta-lenses, including complexity, high costs, and limited responses, constraining their performance and applications. In our research, we introduce innovative tunable water and 3D printing meta-lenses tailored for millimeter waves. This technology empowers the delivery of the focusing spot to arbitrary positions in two-dimensional or three-dimensional space. Notably, it allows the precise transmission of a highly concentrated signal to a specific location, with the added capability of adjusting the transmission direction freely. This breakthrough enables the development of secure, flexible, and highly directive 6G communication systems. Our proposed approach overcomes existing limitations and holds promise for diverse applications in wireless power transfer, zoom imaging, and remote sensing.
