AI Technical Summary
In the existing technology, multi-beam transmissive and reflective integrated metasurface systems have problems such as the lack of a precise mechanism for arbitrary allocation of multi-beam energy in the whole space, the lack of a mathematical model for global amplitude constraints on the transmissive and reflective radiation pattern, and the difficulty in automatically converging the metasurface weight mapping into the optimal physical control command, which leads to instability in the three-dimensional radiation pattern reconstruction process.
By determining the target radiation pattern, obtaining the target mask, initializing the metasurface unit, performing global normalization of the transmission and reflection radiation characteristics, obtaining initial weights, and obtaining reconstructed transmission and reflection weights through amplitude constraints and iterative corrections, and finally outputting physical control commands, high-precision and flexible control of transmission and reflection energy in the entire space and stable reconstruction of the three-dimensional radiation pattern are achieved.
It achieves precise allocation of multi-beam energy across the entire space and stable reconstruction of three-dimensional radiation patterns, improves the generation efficiency and automation level of metasurface physical control commands, and ensures the consistency of the reconstructed radiation pattern with the target model in spatial distribution.
