Composite absorber for electromagnetic waves, a method for the arrangement of the composite absorber and free space with this composite absorber

摘要

Composite absorber for electromagnetic waves, which is produced in that ferrite plates (2) and upper absorber (3), the shape of a flat plate, a wedge or a pyramid, are connected with one another, wherein the upper absorber (3) by dispersing of a ferrite powder in a resin whose dielectric constant at a frequency of at least 1 mhz is not greater than 4,9 is prepared.
