Shielding properties of the (FeIn<sub>2</sub>S<sub>4</sub>)<i>х</i>×(AgIn<sub>5</sub>S<sub>8</sub>)<sub>1-</sub><i>х</i> system in the microwave range
Abstract
The frequency dependences of attenuation and reflection coefficient for solid solutions of the (FeIn2S4)х ×(AgIn5S8)1-х system upon interaction with microwave radiation are obtained. It is established that crystal powders of the mentioned compounds provide attenuation of the electromagnetic radiation from 6 dB till 14 dB in the range 8...12 GHz. With comparative thickness about 1 mm FeIn2S4 compound crystals have the most shielding efficient. The reflection coefficient of such samples can be reduced till -18 dB. With silver ions in solid solution reflection coefficient increases to -1,5…-2 dB.
