摘      要：We demonstrate a neural network capable of designing on-demand multiple symmetry-protected bound states in the continuum(BICs)in freeform structures with predefined *** latent representation of the freeform structures allows the tuning of the geometry in a differentiable,continuous *** show the rich band inversion and accidental degeneracy in these freeform structures by interacting with the latent representation ***,a high design accuracy is demonstrated for arbitrary control of multiple BIC frequencies by using a photonic property readout network to interpret the latent representation.
