The development of a magnetic iron/nitrogen-doped graphitized carbon composite with boosted microwave attenuation ability as the wideband microwave absorber

Abstract

Magnetic carbon based composite has been attractive candidates for the electromagnetic (EM) absorption, due to their dual magnetic and dielectric loss ability. In this work, a novel magnetic carbon has...

Synergetic Dielectric and Magnetic Losses of a Core–Shell Co/MnO/C Nanocomplex toward Highly Efficient Microwave Absorption

“…The undeniable increase in the advanced electronic equipment and communication devices has rendered convenience to human life and improved the work efficiency. − The accompanying electromagnetic leakage and interference can not only interfere with the typical operation of high-precision instruments but also affect human health. , To eliminate electromagnetic wave pollution and signal interference, it is imperative to ingeniously design and develop high-performance microwave-absorbing materials (MAMs) with characteristics of strong absorption, broadband frequency, low thickness, and low density . One-component MAMs barely satisfy the requirement of both broadband and strong absorption in specific frequency ranges .…”
