Carbonization Tuned Core‐Shell Fe3O4@C Nanostructures with Enhanced Electromagnetic Wave Absorption

Advanced Materials Interfaces, EarlyView.
The core‐shell structured Fe3O4@C composites are prepared by employing an in situ polymerization and carbonization treatment method. The effect of carbonization temperature on electromagnetic wave absorption of H‐FO@C composites is symmetrically analyzed, and the impedance matching and attenuation ability are improved significantly by controlling ...

Broadband Interferenceless Perfect Absorption in Hexagonal Boron Nitride and Lithium Fluoride Hyperbolic Metamaterial

Advanced Photonics Research, EarlyView.
The images (a) and (b) illustrate a composite metamaterial with anisotropic permittivity. When incident light, polarized in transverse magnetic or transverse electric modes, enters the structure, the reflectance spectra in (c) and (d) show low reflection and high absorption over a wide range of incidence angles. This behavior has potential applications

Design Method of Time‐Multiplexed Ultrashort Throw Ratio Projection System with Low Distortion and Uniform Resolution

Advanced Photonics Research, EarlyView.
This work develops an ultrashort throw ratio (UTR) laser projection system using time‐multiplexed micro electro mechanical systems scanning. Trapezoidal distortion via vertical laser incidence control is eliminated and a systematic design method integrating a miniaturized catadioptric objective that maintains uniform optical étendue is proposed.
