Time-domain adjoint optimization for metalens design toward enhanced broadband efficiency and uniformity
Summary: We propose a time-domain adjoint optimization method for achromatic metalens design, achieving high efficiency and near-uniform spectral response. Unlike frequency-domain approaches, which require simulations for each sampled frequency, our method evaluates the entire frequency band continu...
