Interface‐Stabilized Glass‐Ceramic/Silver Composite Coatings Enable Predictable Multiband Infrared Stealth Under High‐Temperature Marine Environment

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Infrared (IR) stealth is crucial for improving the survivability of equipment. The growing demand for service in marine environments poses new challenges to the composition and structural design of existing IR stealth coatings. This study first investigates the effects of NaCl/water vapor corrosion on the IR stealth performance of GH3536 and a

High‐Resolution 3‐D Lithospheric Structure of the Subducting Carnegie Ridge and the Ecuadorian Margin Imaged From Teleseismic Receiver Functions

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Ecuadorian margin is a forearc‐arc system shaped by oceanic terrane accretion and Carnegie Ridge subduction, yet the accretion mechanism and ridge subduction extent remain poorly constrained. Using teleseismic P‐wave receiver functions from dense seismic arrays, we image velocity discontinuities within the overriding plate and subducting ...

White light diffraction patterns of amplitude and phase zone plates [PDF]

, 2013
The polychromatic properties of the Fresnel zone plate, Gabor zone plate, phase reversal zone plates and kinoform lens are studied. The polychromatic intensity in the diffraction patterns on these plates has been computed and the influence of Gaussian ...

Hard X-ray nano-holotomography with a Fresnel zone plate [PDF]

, 2020
X-ray phase contrast nanotomography enables imaging of a wide range of samples with high spatial resolution in 3D. Near-field holography, as one of the major phase contrast techniques, is often implemented using X-ray optics such as Kirkpatrick-Baez ...

Three‐Dimensional Array Multicasting of Cylindrical Vector Beams Using Spin‐Multiplexed Dammann Vortex Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
This study demonstrates, for the first time, a 3D volumetric cylindrical vector beam (CVB) multicasting architecture that employs multichannel array modes with an operational dimension of 3 × 3 × 5 as information carriers. This approach offers substantial potential for high‐capacity information dissemination in mode‐multiplexed communication networks ...
