Document Type and Number:
WIPO Patent Application WO/2022/130752
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electromagnetic wave absorber: which has excellent performance with respect to absorbance in response to incidence of high-frequency electromagnetic waves of 60-120 GHz; and which is flexible and can be disposed on a variety of curved surfaces. The foregoing has been acheived by an electromagnetic wave absorber which is a structure formed by folding, in a pleated shape, a sheet 1 that contains an electroconductive material and has a surface resistance of 10-104 Ω/□, wherein said absorber is characterized by being provided with slits 2 punched nonparallel to ridgelines R formed by folding.
