Abstract
A method for producing a wave absorber, which method includes rubbing a mixture of a solidifiable fluid binder and a particulate dielectric loss material on a substrate and solidifying the binder, thereby to laminate a wave absorptive layer on the substrate, and a wave absorber produced by this production method are provided. According to the production method of the present invention, a structure including a dielectric loss material and a binder admixed most preferably for wave absorption can be formed easily into a long sheet or a long belt-like wave absorber.
Claims9
A wave absorber comprising a substrate and a wave absorptive layer comprising a binder and a particulate dielectric loss material, wherein said layer is formed on the substrate by rubbing a mixture of the particulate dielectric loss material and the binder in a solidifiable fluid state, and solidifying the binder.
A wave absorber having a structure comprising a substrate and a wave absorptive layer laminated on the substrate, which layer comprising a particulate dielectric loss material fixed by a binder, wherein the substrate comprises a convex having a shape capable of holding the wave absorptive layer and suppressing release thereof, or a concave optionally penetrating the substrate, or both the convex and the concave, and the wave absorptive layer and the convex or the concave or both the convex and the concave are engaged with each other such that release from each other is suppressed.
