Title:
THIN FILM-LIKE ELECTROMAGNETIC WAVE ABSORBER, GHZ-BAND ELECTROMAGNETIC WAVE DECOUPLING SHEET AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2018060862
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorber capable of achieving high dielectric polarization at a frequency of 1-100 GHz (particularly 5-30 GHz) and hence a high electromagnetic wave absorbing characteristic and facilitating sheet processing suited to a complicated shape of a circuit or the like.SOLUTION: The thin film-like electromagnetic wave absorber is formed so that non-flat stainless-based metal powder is dispersed in acrylic rubber, the stainless-based metal powder is contained in 900-2200 pts.mass to the acrylic rubber 100 pts.mass and the thickness is 0.2-2.0 mm.SELECTED DRAWING: None
