Abstract
The article presents the results of studies of the characteristics of reflection and transmission of electromagnetic radiation screens in the microwave range, which are polymer substrates with multilayer coatings consisting of a layer of magnetic alloy of the Fe–Ni, Fe–Co or Ni–Co systems and an Al or Al–Cu sublayer with a surface resistance of no more than 0.1 Ohm/sq. The application modes for such coatings and screen manufacturing technologies are presented. The effect of the inclusion of Al and Al–Cu sublayers in the coating structure of the screens under consideration on the values of their reflection and transmission coefficients of microwave electromagnetic radiation is investigated. It is established that screens with a Fe–Ni coating have the lowest values of the reflection coefficients of electromagnetic radiation in the frequency range of 2–17 GHz (up to –8.5 dB). At the same time, the transmission coefficient of electromagnetic radiation in the specified frequency range of such screens is –11.8 dB. It was shown that by incorporating Al and Cu sublayers into the coating structure of these screens, their electromagnetic radiation reflectivity in the 2–17 GHz frequency range increases to –0.1 dB, while their transmission coefficient decreases to –31.3 dB. These data can be used in the development of microwave electromagnetic radiation screens with reduced weight and dimensions.
