Computational Intelligence and Neuroscience, Volume 2018, Issue 1, 2018., 2018 In the facial expression recognition task, a good‐performing convolutional neural network (CNN) model trained on one dataset (source dataset) usually performs poorly on another dataset (target dataset). This is because the feature distribution of the same emotion varies in different datasets.

Specialized directional beaming through a metalens and a typical application
Nanophotonics, Volume 7, Issue 1, Page 339-345, January 2018., 2018 Abstract The anomalous beaming effect of the periodic metallic corrugations functioning as a special case of kSP=2π/Λ is discussed and verified by means of both theoretical calculation and experimental probing. A metalens is designed on the basis of the special case. Unlike the conventional beaming of convergence or divergence, the metalens can realize

Reversal Asymmetry of Reciprocal Metasurface Enables Ultra‐Compact Varifocal Reflective Lens
Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.The possibility of breaking the reversal symmetry of a lens without violating reciprocity is demonstrated. The freedom provided is utilized to realize an ultra‐compact reflective varifocal lens‐doublet based on a flat metasurface lens and a piezoelectric actuated micromirror.
