Electromagnetic radiation (EMR) absorbers with geometrical and structure sur-face heterogeneities are investigated. Samples of shields based on dielectric and magnetic powder components and having different surface shape were prepared. Shielding properties of these absorbers such as EMR power attenuation, transmission (S21) and reflection (S11) coefficients in the frequency range of 0.5…18 GHz are shown. Dependencies of the shielding characteristics on the shield thickness and the amount of active substance were obtained. Comparative analysis of the developed novel EMR absorbers was conducted. The transmission coefficient down to -43 dB and the reflection coefficient down to -23 dB in the studied frequency range were obtained. An effective attenuation of electromagnetic power by the developed EMR absorbers has been concluded.
