Advanced Science, EarlyView.In this work, a bioinspired all‐in‐one underwater quality evaluation metamaterial, combining sound attenuation, diffuse reflection, and mechanical robustness, is proposed based on jumping spider locomotion and human skeletal biomechanics. Meanwhile, a CNN‑driven quality evaluation framework is established for theoretically dimension‐reduced ...

Local Optimization of Wave-fronts for high sensitivity PHase Imaging (LowPhi)
, 2019 Phase microscopy is an invaluable tool in the biosciences and in clinical diagnostics. The sensitivity of current phase microscopy techniques is optimized for one specific mean phase value and varies significantly across a given sample.

Advanced Science, EarlyView.This work demonstrates a receiver‐transmitter‐integrated metasurface that decomposes an incident wave into orthogonal components and routes them into separate channels. Inspired by a “Wheel‐of‐Fortune” mechanism, it enables independent control over the amplitude, phase, and polarization of the transmitted wave.

Single freeform surface design for prescribed input wavefront and target irradiance
, 2017 In beam shaping applications, the minimization of the number of necessary optical elements for the beam shaping process can benefit the compactness of the optical system and reduce its cost.

Advanced Science, EarlyView.A speckle correlation centroid localization method (SCCLM) is proposed for non‐invasive tracking of an arbitrary deformable object through scattering media and around corners, requiring no prior information. Its effectiveness is demonstrated not only in tracking hidden objects beyond the memory effect region but also in following objects undergoing ...

Advanced Science, EarlyView.A steric‐hindrance molecular engineering strategy uses dimethyl maleate (DMM) to convert poly(1,4‐butanediol) bis(4‐aminobenzoate) (PBDAB) into a precursor with reduced reactivity via Michael addition, thereby retarding the curing process to form a transparent, ultraflexible, and self‐healable secondary‑amine polyurea (PuSA) with a crosslinked network.

Multifunctional Cascaded Metamaterials: Integrated Transmitarrays
, 2016 Control of electromagnetic waves using engineered materials is very important in a wide range of applications, therefore there is always a continuous need for new and more efficient solutions. Known natural and artificial materials and surfaces provide a

Advanced Science, EarlyView.A protocol of fs‐laser‐induced periodic phase‐transition of 2D‐MoTe2 template, inducing AuNPs@1T’‐MoTe2 nanograting, is developed. The labeled AuNPs@1T’‐MoTe2 substrate conjugated with specialized immunoglobulin G demonstrates an unexpectedly high discrimination accuracy close to unity for serological diagnosis of rheumatoid arthritis by frequency ...
