Double-Layer Type Microwave Absorber Made of Magnetic-Dielectric Composite Material

Synthesis and absorbing mechanism of two-layer microwave absorbers containing flocs-like nano-BaZn1.5Co0.5Fe16O27 and carbonyl iron

“…Many studies were carried out to investigate the electromagnetic and absorption properties of single-layer microwave absorbers employing ferrite, carbonyl iron and other new absorption materials [7e10], but the single-absorbers cannot realize the low reflection in wide band. Few attempts were made to study the absorption properties of doublelayer microwave absorber composed of soft magnetic ferrite and ferroelectric substances [11]. However, the absorber with low reflectivity in wide band cannot be obtained yet.…”
