Exceptional Electromagnetic Wave Absorption in High‐Entropy Carbides Enabled by Lattice Distortion Engineering

Rare Metals, EarlyView.
ABSTRACT The growing concern over human health issues, driven by increasingly severe electromagnetic pollution from 5G communication, has made the urgent development of high‐performance electromagnetic wave (EMW) absorbing materials. Although carbide‐based materials are promising because of their conductive and polarization losses, existing single ...

Noise reduction of electron holography observations for a thin-foiled Nd-Fe-B specimen using the wavelet hidden Markov model

Applied Microscopy
In this study, we investigate the effectiveness of noise reduction in electron holography, based on the wavelet hidden Markov model (WHMM), which allows the reasonable separation of weak signals from noise.

Phase Hologram by Acoustic Metasurfaces

Small Structures, EarlyView.
This work has achieved a breakthrough in holographic communication, realizing phase holographic imaging. The proposed phase holographic concept overcomes the limitations of traditional amplitude holographic energy attenuation. The design of its amplitude compensation method further addresses the key challenge of phase holographic imaging clarity ...

Revisiting PSF models: Unifying framework and high‐performance implementation

Journal of Microscopy, EarlyView.
Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

Phase Modulation for Quadruplex Channels of Arbitrary Orthogonal Polarization States via Bilayer Metasurfaces

Nanophotonics, Volume 15, Issue 2, 27 January 2026.
This work demonstrates a strategy for four‐channel phase modulation and flexible energy distribution of arbitrary orthogonal states of polarization under incomplete polarization conversion conditions. Such a strategy can be implemented through an all‐dielectric free‐standing bilayer metasurface configuration and can be used for multichannel optical ...

Toward a consistent definition of holographic entanglement entropy in de Sitter space

Journal of High Energy Physics
We investigate a new definition of holographic entanglement entropy in the framework of static patch holography for de Sitter space. Using the replica trick and twist operator formalism, we derive an entropy functional in dS3 expressed through de Sitter ...
