Abstract

Electromagnetic interference problems have become an increasing problem with the rapid development of wireless information technologies and electronic devices at high frequency ranges, and this has stimulated much attention. To tackle this challenge issue, the electromagnetic absorbing materials that can attenuate electromagnetic waves are urgently pursued. The desired absorbers should include high-efficiency absorption, wide dissipation band, low cost, and being lightweight. Due to high saturation magnetization and permeability at high GHz frequency, ferromagnetic Ni has been considered as a high efficiency electromagnetic absorption. However, the eddy current effect caused by high electrical conductivity, would limit the application. To tackle this problem, two effective ways including designing hierarchical structure and compounding are explored. This paper reviews the state-of-the-art research in the design of Ni based composites as electromagnetic absorption materials.
