Title:
ANISOTROPIC COMPOSITE MAGNETIC SUBSTANCE AND LAMINATED TYPE RADIO WAVE ABSORBING BODY USING THE SAME AND LAMINATED TYPE ELECTROMAGNETIC SHIELDING BODY
Document Type and Number:
Japanese Patent JP2001217114
Kind Code:
A
Abstract:
To obtain an anisotropic composite magnetic substance, capable of simply setting desired radio wave absorbing performance by adjusting only the thickness of a composite magnetic sheet, controlling the direction of unwanted electromagnetic waves and a laminated type radio wave absorbing body and a laminated type electromagnetic shielding body.
In the anisotropic composite magnetic substance 2 composed of Fe-Si-Al powder, soft magnetic substance powder and a bonding agent, the anisotropic composite magnetic substance 2 is worked into sheets 1, and has magnetic anisotropy in the surfaces of the sheets 1.
