Overview

Randomized trial demonstrates flexible terahertz beam manipulation in metagratings, indicating high efficiency for photonic devices.

Key Points

  • The aim is to develop a flexible metagrating design for efficient terahertz wave manipulation.
  • Fabricated metagratings using photocuring 3D printing technology.
  • Achieved flexible control over energy distribution among diffractive orders by tailoring structural parameters.
  • Experimentally validated terahertz beam steering and flexible spectral tuning.
  • Achieved the highest manipulation efficiency of 95.4% and transmission efficiency of 92.6%.
  • Demonstrated terahertz beam steering with a range of 80°.
  • Realized a maximum frequency shift of 90 GHz in transmission peaks.
