Abstract
It’s proposed to use the water containing powdered perlite to create the electromagnetic radiation (EMR) shields. The frequency dependences of EMR reflection and transmission coefficients, as well as electromagnetic radiation power weakening of frequency range 0,7…17 GHz shields on the basis of this powdered material having different water content values is taken. It is proposed to use a calcium chloride water solutions in concentrations of 10…40 wt. % for perlite impregnation to obtain a stable water content in it. It is shown that increasing in the range of 10 to 40 wt. % of concentration of calcium chloride water solution, used for perlite impregnation reduces the values of the EMR transmission coefficients values of shields based on this material in frequency range of 1,7…3 GHz on 2…20 dB (depending on the perlite fractions size and increment value of calcium chloride water solution concentration). The EMR reflection coefficients values increase in this case on average by 5 dB. Investigated EMR shields can be used in the construction process of rooms, where radioelectronic equipment performing information processing is placed.
