铁凎氧磁物已越来越广泛地运用在微波领域中,它在外加磁场的作用下呈现非互易的性能,能制成各种非互易的微波元件,隔离器是其中最有用的一种。隔离是指电磁波在波导中正方向传输衰减很小,反方向传输则衰减很大。隔离作用可以用不同的方法获得,可以利用铁磁共振现象对微波信号非互易的吸 Ferromagnetic oxygen has become more and more widely used in the field of microwaves. It exhibits nonreciprocal performance under the action of an applied magnetic field and can be used to make various non-reciprocal microwave components. Isolators are the most useful A. Isolation refers to the electromagnetic wave in the positive direction of the waveguide attenuation is small, the reverse transmission is greatly attenuated. Isolation can be obtained in different ways, can use the phenomenon of ferromagnetic resonance of microwave signals are not reciprocal absorption
