Document Type and Number:
WIPO Patent Application WO/2022/265067
Kind Code:
A1
Abstract:
An electromagnetic absorber according to one aspect of the present invention comprises a base material formed of a polymer, and a powder dispersed in the base material. The powder is formed of a Fe-Cr-Co-based alloy having a two-phase separated structure comprising a first phase and a second phase. The Fe content and the Co content of the first phase are more than those of the second phase. The Cr content of the second phase is more than that of the first phase. The two-phase separated structure is a modulated structure. Preferably, the first phase is elongated or flattened.
