Rare Metals, EarlyView.ABSTRACT This study developed a FeSiAl@LMPGP composite material to address the demand for low‐frequency electromagnetic absorption. Through controllable heat treatment, FeSiAl particles and PbO nanoparticles self‐assembled into a high‐density Mott–Schottky heterointerface structure, which exhibited a significant built‐in electric field (BIEF) effect ...

Metasurface Doppler Cloak for Broadband Radar Stealth
Advanced Physics ResearchAbstractConcealing an aircraft is a multi‐faceted endeavor, notably involving radio and infrared frequencies. In a radar stealth context, it often translates to the reduction of the radar cross‐section (RCS). However, other routes that take advantage of radar signal processing exist.
