| Abstract | ||
| Information protection data can be in difference types like data encryption, Protect the building from theft or her direct intervention, shielding equipment and the building of data leakage .Shielding properties of the absorbers with different form of surface such as a regular alternation of rectangular elements and a hemispherical shape have been investigated. Increasing values of electromagnetic radiation EMR attenuation from -5.0 to -30.0 dB with increasing of frequency has been established. Reflection coefficient for the samples of developed constructions from –4 to –15 dB has been obtained. It is shown that the formation of ordered heterogeneities of different shapes can enhance the effectiveness of the shielding parameters for the attenuation and reflection in the microwave | ||
