Structural, magnetic and microwave absorption characteristics of BaCoxMnxTi2xFe12−4xO19

Wideband electromagnetic wave absorber using doped barium hexaferrite in Ku-band

“…Even though many literatures have been reported on the fabrication of single layer wave absorbers [7][8][9][10][11], this is the first research which shows the possibility of fabrication of absorbers with the wideband EM absorption by substituting suitable cations. The current interest is to introduce substitution in barium ferrite which can easily tune the bandwidth of the reflection loss values.…”

“…Recently, we have focused our studies on the microwave attenuation properties of doped barium hexaferrite [9,10]. Even though many literatures have been reported on the fabrication of single layer wave absorbers [7][8][9][10][11], this is the first research which shows the possibility of fabrication of absorbers with the wideband EM absorption by substituting suitable cations.…”

Designed synthesis of wide range microwave absorption Fe3O4–carbon sphere composite

“…In general, microwave absorption materials can be divided into two types: magnetic materials and dielectric materials, which are relevant to magnetic loss and dielectric loss, respectively. Recently, composite microwave absorption materials have attracted much attention due to their enhanced microwave absorption properties, which are relevant to multiform electromagnetic losses based on magnetic or dielectric loss [5][6][7][8][9]3]. We have reported hydrothermal synthesis of well dispersed Fe 3 O 4 nanoparticles and their microwave absorption properties earlier.…”

Fabrication and microwave absorbing properties of Ni–Zn spinel ferrites

“…However, in the microwave region, the applications of spinel ferrites are limited at the lower end of microwave frequency (1-3 GHz) because of their lower natural resonance frequencies in comparison with those of other types of ferrites, such as hexaferrites [24][25][26][27][28][29][30][31][32]. Within the gigahertz range, the permittivity of a ferrite is almost a constant with its imaginary part close to 0.…”
