Transparent Topological Meta-Diplexer via Tightly Confined Valley Surface States. [PDF]
Adv Sci (Weinh)An optically transparent topological metasurface supporting tightly confined valley surface states enables robust and flexible wave routing in an ultrathin platform. A compact transparent meta‐diplexer with spatially and spectrally separated channels is realized, while communication experiments verify high‐fidelity signal transmission, opening new ...

CoSP: Reconfigurable Metamaterial Inverse Design via Contrastive Pretrained Large Language Model. [PDF]
Adv Sci (Weinh)In this work, CoSP (contrastive multi‐state pretrain), an intelligent inverse design method for reconfigurable metamaterials based on a contrastive pretrained large language model, is proposed. Numerical experiments demonstrate that CoSP can design reconfigurable metamaterial structures for multi‐state, multi‐band optical responses, showing great ...

Compressive Imaging of Subwavelength Structures [PDF]
SIAM Journal on Imaging Sciences, 2009 The problem of imaging extended targets (sources or scatterers) is formulated in the framework of compressed sensing with emphasis on subwavelength resolution. The proposed formulation of the problems of inverse source/scattering is essentially exact and leads to the random partial Fourier measurement matrix.
