This study introduces a new type of photonic lattice, the Fourier-component-engineered metasurface, which lacks the first Fourier harmonic component in its lattice parameters. It demonstrates continuous high-Q bound states near second stop bands. The concept of manipulating electromagnetic waves in artificial periodic structures by engineering Fourier harmonic components in periodic modulations is highlighted.
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.
