Shielding and Electromagnetic Radiation-Absorbing Properties of Shugnite-Containing Materials

Finely dispersed shungite is studied as an effective filler for composite materials. Experimental data are obtained on the effect the concentration of the filler of a composite material has on its characteristics of absorbing and shielding from electromagnetic radiation in the radio and microwave ranges. The data can be used to produce effective radio-absorbing materials and electromagnetic screens for protecting information and against unwanted effects of electromagnetic radiation in radio engineering and the military.
