Patent ID: 8466825

Claim:
A combined electromagnetic wave absorber comprising: a magnetic absorber plate; a crossed electromagnetic wave absorber having a plurality of crossed dielectric loss plates disposed perpendicular to the magnetic absorber plate; and a compact electromagnetic wave absorber disposed in a space defined by the dielectric loss plates of the crossed electromagnetic wave absorber on the magnetic absorber plate, the compact electromagnetic wave absorber having a plurality of electromagnetic wave absorbent layers and a low dielectric layer interposed between the electromagnetic wave absorbent layers and having a dielectric constant lower than the electromagnetic wave absorbent layers, the electromagnetic wave absorbent layers and the low dielectric layer being disposed in a direction perpendicular to the magnetic absorber plate, wherein the electromagnetic wave absorbent layers and low dielectric layer are configured such that a synergistic effect is created between, an attenuation effect on the electromagnetic waves by multiple thermal conversions in the electromagnetic wave absorbent layers, and a cancelling effect on at least a portion of the electromagnetic waves due to phase difference.
