我们从理论上研究了混合电磁自旋波在多带阻微波波导中的传播，该波导被构造为反铁磁（AFM1）/介电/反铁磁（AFM2）夹层结构。在系统中发现了以多个衰减峰值为特征的带阻。多个带阻的频率和衰减峰值的强度可以通过外部磁场来操纵。然而，通过调节介电层的厚度或AFM层的厚度，带阻的频率几乎不变，而衰减峰的强度却发生显着变化。这一特征源于微波和自旋波之间的耦合，该耦合与自旋运动的集体激发相关。我们的研究可能会应用于高频微波带阻滤波器的设计。
We theoretically study the propagation of hybrid electromagnetic-spin waves in a multiple-band-stop microwave waveguide, which is constructed as an antiferromagnetic (AFM1)/dielectric/antiferromagnetic (AFM2) sandwiched structure. Band stops, which are characterized by multiple attenuation peaks, have been found in the system. The frequencies of multiple band stops and the intensities of attenuation peaks can be manipulated by external magnetic field. However, by tuning the thickness of the dielectric layer or the thickness of AFM layers, the frequencies of the band stop are almost invariable, while the intensities of the attenuation peaks change significantly. This feature originates from the coupling between the microwave and spin wave associated with the collective excitations of spin motions. Our investigation may potentially be applied to the design of high-frequency microwave band-stop filters.
