Abstract
The paper presents new technique of foil-containing microwave absorbers manufacturing. These absorbers surface is characterized by the periodic structure and contain loop-like irregularities made from foiled polymer material. Electromagnetic radiation absorption characteristics in the frequency range 0.7–17.0 GHz of the experimental samples of the absorbers manufactured in accordance to the presented technique are described in the paper. These characteristics were obtained to experimentally justify the presented technique. The amplitude of the described characteristics changes from 0.5 to 0.95 in frequency ranges 0.7–2.0 GHz, 4.0–16.0 GHz. It means that the absorbers, manufactured in accordance to the presented technique are wide-band. Moreover, these absorbers are characterized by lower weight compared to the analogs. They are prospective for use for development of movable partitions for anechoic chambers.
