Creation of broadband radio-absorbing structures based on frequency-selective gratings with distributed losses

In this paper, we obtained resistive frequency-selective gratings, where a composite (Co40Fe40B20)60(SiO2)40, a chromium film and a two-layer chromium film and a composite were used as a resistive material. Their magnetostatic and magnetodynamic properties were investigated, and a parameter S21 (ref...

Zusammenfassung:In this paper, we obtained resistive frequency-selective gratings, where a composite (Co40Fe40B20)60(SiO2)40, a chromium film and a two-layer chromium film and a composite were used as a resistive material. Their magnetostatic and magnetodynamic properties were investigated, and a parameter S21 (reflection) in an anechoic chamber was measured using two horn antennas. The samples with a resistive film of a nanocomposite (Co40Fe40B20)60(SiO2)40 exhibit significant absorption.
