Advanced Optical Materials, Volume 14, Issue 31, August 21, 2026.Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,

Advanced Photonics Research, Volume 7, Issue 8, August 2026.A plasmonic metasurface comprising gold cylinders of tailored dimensions exhibits simultaneously the generalized Kerker effect and a bound state in the continuum, allowing for a detailed study of the subtle interplay between these phenomena. The numerical simulation results are in good agreement with experimental measurements, and the underlying ...

Intrinsic Focus‐Like Light Concentration From Anti‐Resonant Hollow‐Core Fibers
Advanced Photonics Research, Volume 7, Issue 8, August 2026.The fundamental mode of hollow‐core waveguides is shown to produce intrinsic focus‐like light concentration in free space without external optics. Combined experiments and simulations reveal that this behavior originates from the non‐Gaussian nature of leaky modes, establishing a new mechanism for lensless beam shaping and compact optical interfacing ...

On Determination Method for Resolution of Secondary Electron Images in Scanning Electron Microscopy
Advanced Science, Volume 13, Issue 44, 7 August 2026.An idealized SEM, termed Rayleigh's microscope, is constructed by Monte Carlo simulation to represent imaging conditions that just satisfy the Rayleigh criterion. Based on this physically defined model, sharpness–resolution conversion curves are established and combined with the Rose criterion, enabling automated resolution evaluation from practical ...
