Sub‐100 Nanometer Focusing of Hard X‐rays Using SU‐8 Compound Kinoform Focusing Lenses
Advanced Photonics Research, Volume 7, Issue 4, April 2026.A novel aberration‐free X‐ray compound refractive lens design based on Cartesian oval curve is presented. Achieving a vertical focal spot size of 70.8 nm using knife‐edge scanning with a 200 μm incident aperture. Wavefront reconstruction via knife‐edge imaging further resolves a refined focal spot of 56 nm.

Topological Transitions at Optical Interfaces Near Reflection Singularities
Nanophotonics, Volume 15, Issue 7, 13 April 2026.Topological transitions—from ideal to deformed off‐axis vortices—are revealed near optical reflection singularities. Governed by three independent control parameters (incident angle, incident, and reflected polarization states) and extended to PT‐symmetric multilayer systems, this framework enables precise manipulation of structured light and ...

Dynamic One‐Dimensional Beam Shaping via a Mechanically Tunable Bilayer Metasurface
Nanophotonics, Volume 15, Issue 8, 24 April 2026.We propose a generalized method for designing a bilayer metasurface for mechanically tuning one‐dimensional beams. The lateral displacement between layers directly affects the final phase profile of the system, thereby modulating the beam characteristics. Orthogonal decoupling of the modulation and wavefront shaping enables simple and versatile 1D beam
