Overview

Randomized trial demonstrates enhanced beam scanning in dual-band metasurfaces, suggesting improved communication technology.

Key Points

  • The research aims to develop a programmable metasurface that allows for precise control of electromagnetic wave manipulation.
  • Proposed a guided-wave-driven, liquid-crystal-based metasurface with dual-band, dual-polarisation capabilities.
  • Fabricated an LC-based programmable layer using standard LCD processes and a broadband waveguide feed structure.
  • Utilized a complementary resonance mechanism to maintain consistent meta-atom dimensions across frequency bands.
  • Achieved beam scanning capabilities of up to ±75° at both frequency bands, demonstrating remarkable performance.
  • Enabled controllable near-field focusing through programming of aperture amplitude distribution for precise energy localisation.
  • Surpassed previous designs in terms of dynamic beam scanning and energy management capabilities.
