(B) Schematics of the DNN-based forward prediction model. (C) Predicted angular transmission spectrum of the nonlocal metasurface via DNN. (D) Schematics of the BO method. Recommended structural parameters from BO at fixed λ. (E) Optimized angular transmission spectrum of the nonlocal metasurface via BO.
