Enhanced electromagnetic absorption properties of carbon nanotubes and zinc oxide whisker microwave absorber

Microwave Radar Absorbing Properties of Multiwalled Carbon Nanotubes Polymer Composites: A Review

“…Literature reports show the enhancement of EM absorbing properties of MWCNTs when metals , ferrites , and nonmagnetic structures [91][92][93][94][95][96][97][98][99][100][101][102][103] have been attached. Carbon nanostructures such as graphenes and short carbon fibers have been attached with MWCNTs [104][105][106][107][108][109] to get improved EM absorption properties.…”

Effect of Nd–Co substitution on magnetic and microwave absorption properties of SrFe12O19 hexaferrites

“…Thus, extensive studies on microwave absorption properties of various materials have been investigated to select a suitable absorbent with high absorptive ability and wide band absorption. The most current research focuses on using ZnO composites [4][5][6][7], carbon nanotubes [8,9], ferrites [10,3,11], metal alloys [12] and so on, as absorbents. M-type ferrites have been widely used as microwave attenuation materials and have recently received considerable attention from researchers [13][14][15][16][17] because of their large anisotropy field, high saturation magnetization, and excellent chemical stability.…”

Experimental Determination of the Performance of Rice Husk-Carbon Nanotube Composites for Absorbing Microwave Signals in the Frequency Range of 12.4-18 GHZ

“…CNTs contain a high content of carbon, which is considered to be a lossy conductor material that can help absorb microwave energy [8][9][10][11][12][13]. In addition, several researchers have used CNT composites to develop materials that can be used as shields against electromagnetic radiation [14][15][16][17][18].…”
