High-performance microwave absorption by optimizing hydrothermal synthesis of BaFeO@MnO core-shell composites.

Stealth technology advances in radar-absorbing materials (RAMs) continue to grow rapidly. Barium hexaferrite is the best candidate for RAMs applications. Manganese dioxide (MnO) is a transition metal with high dielectric loss and can be used as a booster for changing polarization and reducing reflection loss.
