Radiotechnical properties of metallized fabrics

Abstract

A number of electromagnetic field shielding materials based on metallized fabric have been produced and investigated. High screening coefficient of the fabrics samples under testing in the frequency range 1×1^–2…1×10⁴MHz shown that these materials can be used in applications where fabric-based high conductivity materials are necessary – design of radioelectronic equipment, radio shielded rooms and anechoic chambers, information safeguard problems, ecology tasks, protection of the personnel against high frequency radiations, etc. Ni-metallized fabrics of different type (polyamide, polyester, silica, glass, cotton and mixed) have been investigated in a frequency range 1 MHz … 1.25 GHz. A protective radio shielding individual set has been designed using some of these metallized materials.
