摘要：

Since ferrites are electromagnetic wave absorbing materials of composition-dependent resonance type, useful frequency ranges are typically narrow. In the present study, laminated electromagnetic wave absorbers composed of ferrite-ferrite or ferrite-dielectric layers were constructed to improve electromagnetic wave absorbing properties. When ferrites of different composition and thickness were layered, center frequency of the laminated ferrite could be changed between the center frequencies of each ferrite. Compared with monolithic ferrites, ferrite-dielectric laminates exhibited broader frequency ranges with 20 dB or more attenuation.
