Abstract

A surrogate model for nanopillar-based meta-atoms has been trained to replaces on-the-fly RCWA computations with precomputed responses.

Use Case

Aberration Control via Metalens

Spherical aberration was corrected using a metalens, which compensated for focal spot broadening seen in a spherical-plano lens.

Use Case

Focusing Metalens Based on Nanopillars

A focusing nanopillar metalens was designed using a pre-trained surrogate model, achieving an output wavefront that reproduces the target spherical phase.
