Optimization for Si Nano-Pillar-Based Broadband Achromatic Metalens

Optimization for Si Nano-Pillar-Based Broadband Achromatic Metalens

An innovative optimization algorithm, named the hybrid particle swarm and genetic algorithm (PSO_GA), is proposed for designing broadband achromatic metalenses. A database is first constructed by scanning the parameters of the unit cell of the metalenses using FDTD software, mapping each unit cell t...
