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.
