Fabrication and electromagnetic characteristics of microwave absorbers containing carbon nanofibers and NiFe particles

Design, fabrication, and characterization of lightweight and broadband microwave absorbing structure reinforced by two dimensional composite lattice

“…tested in laboratories [2][3][4][5][6][7][8][9][10][11][12]. Periodic structures [13,14] and metamaterials [15,16] have also been used to enhance the microwave absorbing performance.…”

Inorganic functional nanofibers: processing and applications

“…Park et al . 66 fabricated the single-layered microwave absorbers employing both dielectric and magnetic lossy materials. CNFs were used as dielectric lossy materials and NiFe particles were used as magnetic lossy materials.…”

Effect of short carbon fibers and MWCNTs on microwave absorbing properties of polyester composites containing nickel-coated carbon fibers

“…In recent years, traditional carbon conductive fillers (for instance carbon black (CB) and short carbon fibers (SCFs)) have been partially replaced by carbon nano fibers (CNFs) and carbon nanotubes (CNTs and MWCNTs) [2,[7][8][9][10][11][12][13] due to their higher aspect ratio and electrical conductivity which result in high EM losses at low filler content along with a reduction of thickness and weight [10,14].…”

“…The magnetic absorbers are generally characterized by higher weight, thinner matching thickness, poorer absorbing characteristics at high frequency and wider absorbing bandwidths in comparison with dielectric ones. To mediate among the advantages and disadvantages of each lossy material, a mixture of both types could be a solution [2]. As magnetic lossy material represents usually the base one, weight can be still a concern.…”
