This study proposed a liquid crystal (LC) millimeter-wave (MMW) metasurface with an orthogonally combined wire grid electrode structure. We aimed to develop reflective LC MMW phase shifters. The reflection phase change under a voltage application was assessed by conducting computer simulations and experimental measurements. Consequently, the reflection phase changed by approximately 300° for a thin LC layer (40 µm) device.
