Abstract:A polarization-independent structural color based on a coding metasurface is reverse designed via a bidirectional neural network. A forward prediction network from coding metasurface structures to colors is constructed by introducing a bidirectional long short-term memory (Bi-LSTM) model. Based on this model, a bidirectional neural network training method is adopted to achieve reverse design from the target color to the optimal structure of the coding metasurface. The results show that the method can achieve 9… Show more
