Broadband achromatic metalens design based on predictive neural network and particle swarm optimization-genetic algorithm

The main challenge in designing broadband achromatic metalenses is to achieve the desired phase distribution at different wavelengths and positions. Finding the exact relationship between phase modulation and the size or shape of individual nanopillars is a critical but time-consuming step. This pap...
