Implication

Randomized trial shows enhanced beam steering in metasurfaces, suggesting cost-effective energy-efficient solutions.

Key Points

The aim is to develop a mechanically programmable metasurface that efficiently steers subterahertz beams without continuous power supply.
Utilized a mechanically latched, programmable metasurface with lead-screw-driven scissor-telescopic mechanism.
Conducted experiments from 110–170 GHz to measure beam steering capabilities.
Focused on power consumption, demonstrating operation with microwatt-level standby electronics.
Achieved continuous beam steering with a 1.2° average pointing error over tested frequencies.
Supported simultaneous steering of up to five beams, with real-time tracking rates of 25°/s.
Demonstrated symbol error rates below 10 −6 in a 150-GHz 16-QAM link with a prototype cost of US$21.12.
