    摘要: Currently approaches for inversely obtaining plasmonic meta unit dimensions for given structural color require a considerably large dataset for inverse prediction. Further, they also suffer from low accuracy in regions corresponding to x and y coordinates proximal to the 45-degree axis in a CIE 1931 colour space i.e., close to the white point. Present disclosure provides method and system for inversely predicting nanofeatures of plasmonic metasurface using remodeled variational autoencoder. The system uses a remodeled variational autoencoder (VAE) network that inversely predicts plasmonic metasurface nanofeatures while providing diversity as well as prediction accuracy. The remodeled VAE network has a probabilistic encoder that maps chromaticity coordinates to a latent space and a probabilistic decoder that maps this latent space back to the coordinates. Further, a multi-layer perceptron layer is added to the latent space that considers the reconstruction as well as dimensional prediction, thereby making training of the network versatile.
