MULTI LAYERED ELECTROMAGNETIC WAVE ABSORBER AND MANUFACTURING METHOD THEREOF CAPABLE OF HAVING BROADBAND ABSORPTION CHARACTERISTICS IN THIN THICKNESS

摘要

PURPOSE: A multi layered electromagnetic wave absorber and a manufacturing method thereof are provided to achieve broadband absorption properties by including a magnetic loss mixture for absorber and a dielectric loss mixture for absorber on an absorption layer.;CONSTITUTION: A multi layered electromagnetic wave absorber(200) includes a surface layer(210), an absorber(220) and a boundary layer(230). The surface layer reduces the wavelength of incident electromagnetic waves. The surface layer includes lossy materials for the surface layer. A dielectric loss mixture for the surface layer is formed by mixing dielectric loss materials, epoxy, a hardener, and solvent. The absorber includes lossy materials for the absorber. The boundary layer reflects the electromagnetic wave by shielding the transmitted electromagnetic wave.;COPYRIGHT KIPO 2012
