FIELD: radio engineering; electromagnetic wave absorbers.
SUBSTANCE: proposed electromagnetic wave absorber that can be used in aerospace engineering for absorbing electromagnetic waves of broad frequency band reflected from metal structural components (to eliminate distortion of antenna directivity pattern caused by echo signal) and can be disposed on flat and curvilinear surfaces, and also can be incorporated in structural components as supporting member has cellular structure made in the form of stack of hollow prisms whose material does not reflect radio waves; its walls are covered with nonmagnetic coating. Top and bottom ends of prisms are disposed in parallel planes.
EFFECT: facilitated manufacture, reduced mass, enlarged functional capabilities.
