论文摘要
常规的光子晶格（例如超材料和光子晶体）具有各种有趣的物理特性，这些特性归因于晶格参数的定期调制。在这项研究中，我们介绍了新型的光子晶格类型，即傅立叶成分工程的元图，它们在晶格参数中没有第一个傅立叶谐波分量。我们证明，这些元信息在第二停靠频段附近支持连续的高$ q $绑定状态。定期调制中工程傅立叶谐波组件的概念为操纵人工周期性结构中的电磁波提供了一种新方法。
Conventional photonic lattices, such as metamaterials and photonic crystals, exhibit various interesting physical properties that are attributed to periodic modulations in lattice parameters. In this study, we introduce novel types of photonic lattices, namely Fourier-component-engineered metasurfaces, that do not possess the first Fourier harmonic component in the lattice parameters. We demonstrate that these metasurfaces support the continuous high-$Q$ bound states near second stop bands. The concept of engineering Fourier harmonic components in periodic modulations provides a new method to manipulate electromagnetic waves in artificial periodic structures.
