Abstract. A method for producing of multilayer flexible electromagnetic shields based on powdered charcoal and foiled materials has been developed and substantiated. The frequency dependences of electromagnetic radiation reflection and transmission coefficients in the range of 0.7...17 GHz of screens obtained in accordance with the developed method are investigated. On the basis of such a study results, it has been established that, compared with analogues, these screens are characterized by lower values of electromagnetic radiation reflection coefficient at comparable transmission coefficient values. It is shown that by adding powdered electrocorundum to their composition, it is possible to provide an additional decrease (on average by 5 dB) of electromagnetic radiation reflection coefficient values.

Keywords: titanium dioxide, charcoal, quartz sand, reflection coefficient, transmission coefficient, electrocorundum, electromagnetic shield.
