波導磁振子學是在波導架構中研究磁振子與電磁場之間交互作用的新興研究領域。我們將一顆巨觀的釔鐵石榴石球體直接整合至微波波導中，建立球體內磁振子共振與波導微波光子之間強且高度可調控的耦合。此架構能夠精確控制磁振子與光子的相干耦合，形成對經典與量子資訊處理皆至關重要的混合系統。此外，這類開放式巨觀系統提供了一個極佳的平台，可用於研究非厄米動力學、例外點以及連續譜中的束縛態等先進波動現象。最終，波導磁振子學結合固態磁學與微波工程，為發展下一代相干資訊技術奠定重要基礎。

In the framework of waveguide magnonics, our system explores the interaction between magnons and electromagnetic fields. By directly integrating a macroscopic Yttrium Iron Garnet (YIG) sphere into a microwave waveguide, we establish strong and highly tunable coupling between the magnonic resonances within the sphere and the waveguide microwave photons. This architecture enables the precise control of coherent magnon-photon coupling, leading to hybrid systems critical for classical and quantum information processing. Furthermore, these open macroscopic systems provide an excellent platform for investigating advanced wave phenomena, including non-Hermitian dynamics, exceptional points, and bound states in the continuum. Ultimately, waveguide magnonics bridges solid-state magnetism with microwave engineering to develop next-generation coherent information technologies.
