In this study, we propose a liquid crystal (LC) millimeter-wave (MMW) metasurface with orthogonal wire-grid (OWG) electrodes having two different strip widths electrodes as a reflective LC MMW phase shifter that exhibits large phase variations. As a result, experimental verification confirmed that the reflection phase varies by up to 423°.
