Title:
MATERIAL CONTAINING ELECTROMAGNETIC WAVE ABSORBER AND METHOD FOR PRODUCING THE SAME AND METHOD FOR MANUFACTURING STRUCTURE USING IT
Document Type and Number:
WIPO Patent Application WO/2003/032439
Kind Code:
A1
Abstract:
A material produced by integrating an electromagnetic wave absorber around a granular material, a material produced by dispersing and integrating an electromagnetic wave absorber internally, and a material produced by admixing an electromagnetic wave absorber to a basic material to form countless air gaps and dispersing the electromagnetic wave absorber to a sidewall part surrounding the air gap. A structure is made by mixing a granular material of the electromagnetic wave absorber to constitute a structure distributed uniformly with the electromagnetic wave absorber. A material for bonding aggregate is mixed with the electromagnetic wave absorber to produce a granular material and the bonding material is fused while being mixed with the aggregate and then solidified to constitute a structure distributed uniformly with the electromagnetic wave absorber.
