Microwave absorption properties are studied for flexible materials based on periodic gratings made of carbon nanotube (CNT) threads. Resonant absorption is observed by free space measurements in the frequency range from 26.5 to 40 GHz. Materials comprised of CNT thread gratings with different periods, a metal backplate, and an intermediate dielectric layer exhibit significant reflection losses (less than −45 dB). The shifts of peaks on the absorption spectra caused by changes in the thickness and rotations of the samples indicate the high sensitivity of the obtained results. [ABSTRACT FROM AUTHOR]
