Abstract
A reconfigurable intelligent metasurface with adjustable 3-bit dual-polarization phases may include a plurality of reconfigurable intelligent metasurface units with adjustable 3-bit dual-polarization phases. Each of the plurality of reconfigurable intelligent metasurface units may include: a first layer including four fan-shaped metal patches and four Y-shaped metal patches symmetrical about a center, a second layer being a feeding layer along the x-axis direction, a third layer being a feeding layer along the y-axis direction, and a fourth layer being a metal ground layer. By changing a voltage value at two ends of each of the varactors in an orthogonal polarization direction, the reconfigurable intelligent metasurface unit may be enabled to independently implement dual-polarization 3-bit phase modulation in two orthogonal polarization directions, thereby implementing decoupling in the orthogonal polarization directions.
