摘要:

传统的光子晶格,如超材料和光子晶体,表现出各种有趣的物理特性,这归因于晶格参数的周期性调制。在这项研究中,我们介绍了新类型的光子晶格,即傅立叶组件工程超颖表面,不具有晶格参数中的第一傅立叶谐波分量。我们证明,这些超颖表面支持连续的高$Q$第二阻带附近的束缚态。周期调制中的工程傅里叶谐波分量的概念为在人工周期结构中操纵电磁波提供了一种新的方法。

英文摘要:

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.
