Advanced Optical Materials, Volume 14, Issue 40, 27 October 2026.A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Beam-Scanning Reflectarray Based on a Single Varactor-Tuned Element
International Journal of Antennas and Propagation, 2012 A single varactor-tuned element is investigated as effective solution for the realization of reconfigurable reflectarray antennas. The proposed configuration is successfully implemented for the design of an X-band reflectarray prototype of 3×15 radiators.
