What the study reports
The platform combines an FPGA-controlled digital metasurface with compact low-temperature co-fired ceramic rectennas. The meta-atoms provide a reported 180 degrees plus or minus 5 degrees of phase modulation across 5.0–6.25 GHz, and the system changes beam direction and target count on a millisecond timescale. At 5.8 GHz, the 18 by 18 mm rectenna reaches a reported RF-to-DC conversion efficiency of 70.5%. Experiments compare reconfigurable multi-target delivery with static metasurface configurations. [1]
What this does not establish
The 70.5% value describes RF-to-DC conversion of the reported rectenna under specified test conditions, not wall-plug or end-to-end system efficiency. Compatibility with the 5G NR frequency range does not establish standards certification or coexistence performance. Transfer range, delivered DC power, exposure limits, tracking overhead and efficiency when sharing power among moving receivers must be evaluated for each application.
Our engineering reading
In our interpretation, the strongest system contribution is the co-design of a reconfigurable transmitter and a miniaturized receiver. Practical wireless-power networks will be judged by end-to-end efficiency and useful delivered power under changing geometry, rather than beam agility alone.
