Description

Nkimbeng and co-authors design a miniaturized surface that converts radio wave polarization in this 2025 paper. Their single-layer metasurface turns linear polarization into circular polarization across a wide band. The repeating unit uses meandered metal strips with carefully placed gaps.

The winding shape raises inductance, shrinking the electrical size while keeping conversion strong. The device works from 5.23 to 12.85 gigahertz, an 84.3 percent fractional bandwidth, for waves arriving from either orientation. It holds up at steep angles, up to 85 degrees in one mode, and stays very thin. Simulations and lab measurements agree. Such converters serve antennas and satellite links that need compact, wideband parts.
