Performance of The Heterogeneous Surfaces forElectromagnetic Absorbtion and Information Protection

Information protection data can be in difference types like data encryption,Protect the building from theft or her direct intervention, shielding equipment and thebuilding of data leakage .Shielding properties of the absorbers with different form ofsurface such as a regular alternation of rectangular elements and a hemisphericalshape have been investigated. Increasing values of electromagnetic radiation EMRattenuation 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 dBhas been obtained. It is shown that the formation of ordered heterogeneities ofdifferent shapes can enhance the effectiveness of the shielding parameters for theattenuation and reflection in the microwave.
