Wideband absorption with low-frequency compatibility is always challenging for developing high-performance electromagnetic wave (EMW) absorbing materials. With magnetic loss and a sufficient polarization interface, ferrite materials are promising candidates overcoming this challenge. To address impedance matching issues, carrier material uniform pore distribution, namely, diatomite, employed, resulting in unique three-dimensional biomimetic structure. A sea urchin-like nanomaterial composed of one-dimensional nanorod-shaped Fe3O4 (sea nano-Fe3O4) presented, demonstrating outstanding performance EMW absorption. The optimized Fe3O4@FeP sample exhibits two peaks spanning the C Ku bands when thickness 5.35 mm. experimental results show that nano-Fe3O4 achieves an astounding reflection −60 dB at 6 GHz 3.9 mm maximum effective bandwidth 4 1.7 This design holds significant potential applications.

The intensification of electromagnetic (EM) pollution and the development military detection technology have put forward higher requirements for EM functional materials. Herein, molybdenum diselenide@reduced graphene oxide (MoSe₂@rGO) assembled architecture are constructed, where MoSe₂ nanosheets grow uniformly on rGO sheets. By regulating contributions conduction genes polarization genes, adjustable functions MoSe₂@rGO hybrids can be achieved. reflection loss sample reach −68.7 dB at a thickness 2.32 mm, maximum effective absorption bandwidth 5.04 GHz. When dominate, exhibit 98.7% interference (EMI) shielding efficiency. design energy conversion device results radar cross section (RCS) simulation demonstrate practical application potential material.
