4B4_0635_ TEXTILE METAMATERIALS

Abstract

Metamaterials are media whose properties result more from the distribution of elements than from the chemical composition. Their structural parts need to be smaller than the wavelength. This publication presents the results of the development of metamaterials based on a nonwoven fabric made of polypropylene and flax fibres and their blends. The structural elements were copper split ring resonators (SRR) with dimensions and position on the nonwoven fabric’s surface enabling the reaction to an electromagnetic wave with a frequency around 10 GHz. One- and multiple-layer metamaterials with SRR arrays, imitating the crystal lattice band were studied. The calculation results coincided with the experimental ones.
