Представлены установленные экспериментальным путем закономерности изменения характеристик отражения, передачи и поглощения электромагнитного излучения в диапазоне частот 2,0–17,0 ГГц материалов. Эти материалы содержали порошкообразный активированный березовый уголь, пропитанный водными растворами хлоридов (хлорид кальция, хлорид магния и хлорид натрия). С использованием установленных закономерностей определено, что материалы на основе порошкообразного активированного березового угля, пропитанного водным раствором хлорида кальция, являются радиопоглощающими в случае, если они взаимодействуют с электромагнитным излучением в диапазонах частот 3,5–4,5 и 5,5–17,0 ГГц. В свою очередь материалы на основе порошкообразного активированного березового угля, пропитанного водными растворами хлоридов магния и натрия, являются радиопоглощающими в случае, если они взаимодействуют с электромагнитным излучением в диапазонах частот 2,0–17,0 и 2,0–7,5 ГГц (раствор хлорида магния), 10,0–17,0 ГГц (раствор хлорида натрия). Значения коэффициента поглощения электромагнитного излучения исследованных материалов достигают 0,95. Исследуемые материалы представляются перспективными для изготовления перегородок, предназначенных для экранирования секторов помещений, где располагаются приборы электронной техники, чувствительные к воздействию электромагнитных помех.

The experimentally established regularities of changes in electromagnetic radiation reflection, transmission and absorption characteristics in the frequency range of 2.0–17.0 GHz of materials are presented. These materials contained powdered activated birch charcoal impregnated with chlorides aqueous solutions (calcium chloride, magnesium chloride and sodium chloride). Using the established regularities, it was determined that materials based on powdered activated birch charcoal impregnated with calcium chloride aqueous solution are radioabsorbing if they interact with electromagnetic radiation in the frequency ranges of 3.5–4.5 and 5.5–17.0 GHz. In turn, materials based on powdered activated birch charcoal impregnated with magnesium and sodium chlorides aqueous solutions are radioabsorbing if they interact with electromagnetic radiation in the frequency ranges of 2.0–17.0 and 2.0–7.5 GHz (magnesium chloride solution), 10.0–17.0 GHz (sodium chloride solution). Electromagnetic radiation absorption coefficient values of the studied materials reach 0.95. These materials seem promising for the manufacture of partitions to shield sectors of premises where electronic devices sensitive to electromagnetic interference are located.
