Abstract
Patterns of changes in the characteristics of electromagnetic radiation absorption in the frequency range of 2–17 GHz were established and substantiated for three types of flexible electromagnetic shields. These shields were multilayer composite materials, the middle layer of which consisted of mesh fabric and synthetic padding impregnated with graphite lubricants SDM (type 1) and VMPAVTO (type 2), respectively, as well as of fabric and synthetic padding connected together, impregnated with graphite lubricant FAVORIT (type 3). The outer and inner layers of the electromagnetic shields were fragments of synthetic padding. The average value of the absorption coefficient of electromagnetic radiation in the effective absorption band in the frequency range of 2–17 GHz for the studied shields of various types was 0.61, 0.60, and 0.59 relative units, respectively. The maximum absorption coefficient value (0.77 relative units) was demonstrated by type 1 shields. The proposed flexible electromagnetic shields in the form of multilayer composite materials can be used to ensure electromagnetic compatibility of electronic devices and microwave devices.
