Description
Dunyu Chang and co-authors present a 2026 engineering design for harvesting radio-frequency energy and converting it into direct current. Their device is a flat metasurface, a patterned sheet that interacts with radio waves, fitted with a rectifier circuit. Four symmetrical T-shaped slots in each unit cell trap unwanted harmonic signals produced by the rectifying diode.
Because suppression is built into the surface, no extra filter parts are needed, and the single-layer layout keeps the device compact. Simulations reached a conversion efficiency of 75.6 percent across wide arrival angles and varied wave orientations. Small prototype arrays confirmed that the design scales, which suits wireless power delivery for compact electronics and connected devices.
