摘要： In a facade construction of high-rise structures, a corresponding layer construction is provided for suppressing reflections of incident electromagnetic waves, particularly of radar waves. For this purpose, an electrical resistance layer which has a surface resistance in the range of 300 to 1200 .OMEGA. is arranged at a distance from a reflecting surface. The distance between the reflecting surface and the electrical resistance layer is approximately 1/4 of the wavelength in the propagation direction of incident electromagnetic waves to be suppressed.

摘要： It is intended to arrange a thermal barrier layer ahead of structural parts reflecting electromagnetic waves in the region of radar waves, in order to provide an absorption or a reduction of the reflection. For this purpose electrically and/or magnetically conductive materials are embedded in a material from an electric insulator for forming conductive regions. The dimensions of these conductive regions are in all planes at least a thousand times smaller than the wavelengths of the waves to be absorbed, wherein the electrically and/or magnetically conductive materials comprise a share of up to 10% of the volume of the thermal barrier layer. Herein it is provided to design the upstream cover from an electric insulator.

摘要： A rotor blade comprising fiber-reinforced plastic for a wind power plant is provided with a radar absorber embedded into the fiber-reinforced plastic. The rotor blade includes a layer close to the surface with a defined electrical sheet resistivity of 100 to 800 ohm/square, which is located at a depth of 2 to 5 mm below the surface. The rotor blade also includes a layer far removed from the surface with a defined electrical sheet resistivity of at a maximum 50 ohm/square at a distance to the layer close to the surface of 5 to 16 mm. The integrated radar absorber covers one or several discrete surface sections of the rotor blade, without covering the entire surface of the rotor blade.

摘要： Flat panel elements are placed ahead of structural parts reflecting electromagnetic waves, in the region of radar waves, in order to provide an absorption or reduction of the reflection. For this purpose electrically and/or magnetically conducting materials are embedded into an insulating material in order to form areas of conductivity. The dimensions of these areas of conductivity in all planes are at least 1000 times smaller than the wavelength of the waves to be absorbed, and the electrically and/or magnetically conducting materials amount up to 40% of the weight of the panel area elements.
