Abstract:
An electromagnetic wave absorption panel for absorbing waves incident on said panel at a point of incidence, said panel comprising:a building support element;a reflective element supported by said support element; anda plurality of absorber elements supported by said support element, said absorber elements located closer to said point of incidence of said electromagnetic wave on said panel than said reflective element, said absorber elements stacked in a direction perpendicular to said reflective element and all of said absorber elements being on the same side of said reflective element with respect to said point of incidence, and each of said absorber elements comprising a first layer comprising a ferrite and a second layer comprising a low dielectric constant material, said second layer being different from said first layer in composition and at least one physical property that can affect an electromagnetic wave, and in each of said absorber elements said second layer located farther from said point of incidence of said electromagnetic wave than said first layer.
