摘要

电磁辐射(EMR)在0.7…17频率范围内的反射和透射特性基于粉末珍珠岩和钛磁铁矿的表面几何不均匀(金字塔)形式的屏蔽的GHz取决于这些不均匀的高度。结果表明，这些屏蔽体的EMR反射系数和透射系数值比原屏蔽体大5倍。在珍珠岩和钛磁铁矿混合物的基础上制造的具有平坦表面的屏蔽比类似值低10 dB。

Electromagnetic radiation shields with geometrically inhomogeneous surface based on powdered perlite and titanomagnetite

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.
