Design of Metasurface with Near Couplings Based on Deep Learning Driven Space Mapping

Near couplings will lead to low efficiency electromagnetic waves manipulation of the metasurface. In this paper, a space mapping design framework driven by deep learning is proposed for the optimization of metasurafce with near couplings meta-atoms. The deep learning neural network is training to predict the phase of the atom accurately, in which process the near couplings of the designed meta-ato...
