使用正交相位时变平板谐振器的非互易性
Non-reciprocity using quadrature-phase time-varying slab resonators
摘要：
在本文中，它表明，非互易性可以观察到在时变介质中，而不采用时空调制的折射率。我们表明，通过只使用两个一维的法布里-珀罗板的时间周期的折射率具有正交相位差，它是可能实现相当大的非互易性在入射频率的传输。为了分析这种情况下，广义传递矩阵被引入到所有空间中的所有谐波的波幅。通过内部FDTD模拟验证了结果。此外，为了有一个简单的模型，这样的时变平板谐振器，时间扰动耦合模理论的多谐振，它表明，通过这种方法和解析方法得到的结果是非常一致的。
英文摘要：
In this paper, it is shown that non-reciprocity can be observed in time-varying media without employing spatio-temporal modulated permittivities. We show that by using only two one dimensional Fabry-Perot slabs with time-periodic permittivities having quadrature phase difference, it is possible to achieve considerable non-reciprocity in transmission at the incidence frequency. To analyze such scenario,generalized transfer matrices are introduced to find the wave amplitudes of all harmonics in all space. The results are verified by in-house FDTD simulations. Moreover, in order to have a simple model of such time-varying slab resonators, a time-perturbed coupled mode theory is developed for multiple resonances, and it is shown that the results obtained by this method and the analytical method are in excellent agreement.
