Additive Manufactured Multi-Material 3D metasurfaces for broadband achromatic electromagnetic focusing

In this paper, a broadband achromatic focusing metasurface design scheme based on the equivalent circuit theory and optimized by a deep learning method is proposed. The designed metasurface element consists of multilayer metal rings and a grounding layer, and the phase modulation effect of achromati...
