论文摘要
我们预测磁极极化状态在特殊线上被多个磁体加载时在微波腔中单向循环。现实的有限元数值模拟，包括介电，时间依赖性和非线性效应，证实了完全分析输入输出模型的近似值的有效性。我们发现，分阶段的天线阵列可以将所有功率聚焦于具有控制方向的连贯微波梁和与磁体数量缩放的强度。
We predict magnon polariton states circulating unidirectionally in a microwave cavity when loaded by a number of magnets on special lines. Realistic finite-element numerical simulations, including dielectric, time-dependent and non-linear effects, confirm the validity of the approximations of a fully analytical input-output model. We find that a phased antenna array can focus all power into a coherent microwave beam with controlled direction and an intensity that scales with the number of magnets.
