Spherical Phase Metalenses: Intrinsic Suppression of Spherical Aberration via Equiphase Surface Modulation
Xiaohui Yang, Lei Yang, Xinhui Lu +1
Recent progress in large-scale metasurfaces requires phase profiles beyond traditional hyperbolic designs. We show hyperbolic phase distributions cause spherical aberration from mi…

X-ray Near Field Speckle: Implementation and Critical Analysis
Xinhui Lu, Simon GJ Mochrie, S. Narayanan +2
We have implemented the newly-introduced, coherence-based technique of x-ray near-field speckle (XNFS) at 8-ID-I at the Advanced Photon Source. In the near field regime of high-bri…
