“…The microwave absorbers find applications in EMI shielding, anechoic chambers, cavity resonators and prevention of target detection from RADAR (Vinoy andJha 1995, Dixon 2012). Hexaferrite materials, such as Strontium hexaferrite, Barium hexaferrite etc have been largely studied in literature for microwave absorption properties (Tyagi et al 2010, Trukhanov et al 2017, Tyagi et al 2018. Due to high magnetic anisotropy, hexaferrite materials find applications in high frequency region.…”

M-type barium hexaferrite (BaFe 12 O 19 ) particles are synthesized by using sol-gel auto-combustion reaction for microwave absorption study in X-band. Three different materials namely BaNd 0.02 Fe 11.98 O 19 (Nd2), BaNd 0.04 Fe 11.96 O 19 (Nd4) and BaNd 0.06 Fe 11.94 O 19 (Nd6) have been developed by varying doping of neodymium in barium hexaferrite. The synthesis of particles has been confirmed using SEM micrographs and XRD diffraction pattern. The hysteresis study is carried out for saturation magnetization using vibrating sample magnetometer (VSM). As the doping concentration of neodymium increases, the saturation magnetization of the material is decreased from 47.272 emu g −1 to 16.479 emu g −1 . The vector network analyzer (VNA) is used for complex permittivity and complex permeability measurements of the developed materials. Nd4 material shows highest values of permittivity and permeability losses among other developed materials. From the complex permittivity and complex permeability, the reflection loss results of the developed materials have been calculated. The maximum reflection loss of −33.17 dB was obtained for 2.2 mm pallet of BaNd 0.04 Fe 11.96 and −10 dB bandwidth reaches 2.94 GHz.

Barium titanate (BaTiO3)-polyvinyl butyral (PVB) composites at various weight concentrations were prepared via ultrasonic probe sonicator. The sonication was carried out at 20 kHz and 70% amplitude for about 2 h and BaTiO3 nanoparticles were dispersed well in the mixture of PVB/ethanol under probe sonication. As a microwave absorbent, the microwave absorbing properties of the BaTiO3 nanoparticle-PVB composites with different mixture ratios of 5 wt.% (RAM1), 10 wt.% (RAM2) and 15 wt.% (RAM3) BaTiO3 were investigated based on transmission line theory in the frequency range from 1 GHz to 14 GHz. The minimum reflection loss (RL) of the RAM1 reaches −3.47 dB at 5.57 GHz with a matching thickness of only 7.0 mm. For RAM2 with 4 mm and 4.2 mm thickness ( tm), the RL values are less than −10 dB obtained in the frequency 10.3–13.4 GHz. The RAM3 composite with 15 wt.% BaTiO3 mixture ratio shows a minimum reflection loss of −43.8 dB at 11.01 GHz with a −15 dB bandwidth over the extended frequency range of 10.2–13.2 GHz for a thickness of 2.8 mm and −44.2 dB at 4.77 GHz for a thickness of 6.5 mm.

“…Recently, a study showed the electrical behavior of CNT-filled 3D printable UV resin where the electrical conductivity of the printed parts was increased as a result of increased CNT content [ 148 ]. Several studies on the radar absorptivity of CNT-filled polymer composites have been conducted in the past [ 149 , 150 , 151 , 152 , 153 , 154 , 155 , 156 , 157 ]. In a recent study, radar absorbing composites were printed with SLA technology [ 158 ] where maximum absorption was found for 1.5% multi-walled CNT (MWCNT) filled composites.…”
