Abstract :
The electromagnetic radiation (EMR) reflection and transmission characteristics in the frequency range 0.7...17 GHz for shields with the surface in the form of geometric inhomogeneities (pyramids) based on powdered perlite and titanomagnetite depending on the height of these inhomogeneities are obtained. It is shown that EMR reflection and transmission coefficients values of these shields by 5...10 dB lower than similar values for shields with a flat surface, manufactured on the base of perlite and titanomagnetite mixture.
