Sensing and phase modulation integrated reconfigurable intelligent metasurface insensitive to polarization

The invention discloses a sensing and phase modulation integrated reconfigurable intelligent metasurface insensitive to polarization, and the intelligent metasurface comprises N * N basic units which are periodically arranged, and each basic unit is regulated and controlled by different control signals. According to the invention, the Pin tube is introduced as an adjustable device, so that the phase of the reflected wave of the electromagnetic wave incident to the device realizes two states with the phase difference of 180 degrees, and the phase control is accurate and can be quickly switched; the metal patches and the thin metal strips which are symmetrical to the x axis and the y axis are introduced to serve as the first layer structure, so that the antenna can work under the conditions of normal incidence and oblique incidence, and is not sensitive to the polarization direction of incident waves. According to the invention, the design of asymmetric slotting is introduced, so that the sensing unit can ensur
