Experimental data on the influence of the filler concentration of the composite material on its electromagnetic radiation absorbing and shielding characteristics in the radio and microwave ranges are obtained. The obtained data can be used for manufacturing effective radio-absorbing materials and electromagnetic shields for protection against undesired effects of electromagnetic radiation, information protection, in radio engineering, as well as in warfare.</p></abstract><trans-abstract xml:lang="ru"><p>Исследован мелкодисперсный шунгит в качестве эффективного наполнителя композиционных материалов. Получены экспериментальные данные о влиянии концентрации наполнителя композиционного материала на его поглощающие и экранирующие электромагнитное излучение характеристики в радио- и СВЧ-диапазоне. Полученные данные могут быть использованы для изготовления эффективных радиопоглощающих материалов и электромагнитных экранов для защиты от нежелательного воздействия электромагнитного излучения, защиты информации, в радиотехнике, а также в военном деле.</p></trans-abstract><kwd-group xml:lang="en"><kwd>shungite</kwd><kwd>electromagnetic radiation shields</kwd><kwd>radio-absorbing coatings</kwd><kwd>composite materials</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>шунгит</kwd><kwd>экраны электромагнитного излучения</kwd><kwd>радиопоглощающие покрытия</kwd><kwd>композиционные материалы</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Кукина О.Б. // Научный вестник Воронежского ГАСУ.
