It is shown that a coating of this type with a thickness of 1...2 mm makes it possible to lower by 10...30 dB the first (from large angles) maximum on the angular dependence of backscattering at ultrahigh frequencies in a band of the order of an octave.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты численного расчета обратного рассеяния при больших углах падения плоских волн <italic>TM</italic>-поляризации на протяженную металлическую поверхность конечных размеров с радиопоглощающим покрытием на основе структуры искусственного магнитного проводника.
