Development of Fe‐Based Amorphous/Nanocrystalline Alloys for Electromagnetic Interference Mitigation
ABSTRACT Growing concerns about electromagnetic radiation from communication technologies such as 5G have prompted a search for effective microwave‐absorbing materials to mitigate potential health risks. This study focuses on the development of Fe‐based amorphous/nanocrystalline alloys as microwave absorbers, with specific emphasis on achieving cost‐effectiveness, reduced thickness, and superior absorption capabilities. FePC alloy powders, treated through thermal annealing and ball milling (synergistic processing), exhibit enhanced saturation magnetization and superior microwave absorption properties. The powders, with small particle sizes and high surface areas, demonstrate excellent absorption, achieving a minimum reflection loss (RL) of −30.1 dB at 12.8 GHz with a 5.3 GHz absorption bandwidth at 2 mm thickness. The results highlight the promising potential of these materials for practical applications in reducing electromagnetic interference, offering a combination of high performance, low cost, and easy processing.
