Tailoring tactics for optimizing microwave absorbing behaviors in ferrite materials

Enhanced X and Ku band microwave absorption powered by a magnetic–dielectric synergistic effect in Pr-doped M/W composite hexaferrites

“…However, the average grain size of MW(1 : 1) is much larger, and the total interface area is greatly reduced, which results in the weakening of interface polarization. 50 We note that the complex permittivity of MW(1 : 1) is much higher than that of WM(1 : 1). It can be explained by the enhanced polarization and conduction loss caused by strong interface bonding and larger intergranular contact area, considering the previous analysis.…”

MoS2-Based Nanocomposites for Microwave Absorption: A Review

“…At present, stealth materials have been widely used in aircraft, main battle tanks, ships, arrows, and bombs . For ground weapons, it is important to prevent attacks by airborne radar or infrared detection, radar-guided weapons, and laser-guided bombs . Importantly, for combat aircraft, it is mainly to prevent the detection of airborne early warning aircraft radar, airborne fire control radar, and infrared equipment …”

Polypyrrole/NiFe-layered double hydroxide composite as an anticorrosive microwave absorber

“…1–8 To address these problems, great efforts have been focused on the development of microwave absorbing materials (MAMs). To date, a variety of high-performance microwave absorbers have been designed, such as ferrites, 9,10 ceramic materials (Al 2 O 3 and SiC), 11–13 conductive polymers (polypyrene and polyaniline), 14,15 and carbon materials (carbon nanofibers and graphene). 16,17 In these studies, considerable attention was paid to improving the reflection loss (RL) and effective absorption bandwidth (EAB) of MAMs.…”
