AI Technical Summary
Existing radio wave reflectors struggle to achieve a sufficient phase change in reflected waves, limiting their ability to control the direction of radio wave reflection effectively.
A radio wave reflector design featuring a first substrate with patch electrodes arranged in a matrix, a second substrate with a common electrode, and a liquid crystal layer between them. The patch electrodes have slots, and by adjusting the voltage applied to the liquid crystal layer, the reflection phase of radio waves can be controlled, enhancing the phase change of reflected waves.
The proposed design significantly increases the amount of phase change of reflected waves, allowing for more precise control over the direction of radio wave reflection while maintaining reflection efficiency comparable to existing designs.
