Band dynamics accompanied by bound states in the continuum at the third-order point in leaky-mode photonic lattices
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
Bound states in the continuum (BICs) and Fano resonances in planar photonic lattices, including metasurfaces and photonic crystal slabs, have been studied extensively in recent yea…
Anisotropic metallic metasurface superlattices supporting Fano resonances and bound states in the continuum
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
A perfect metal film with a periodic arrangement of cut-through slits, an anisotropic metallic metamaterial film, mimics a dielectric slab and supports guided electromagnetic waves…
Bound states in the continuum accompanied by avoided crossings in leaky-mode photonic lattices
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
When two nonorthogonal resonances are coupled to the same radiation channel, avoided crossing arises and a bound state in the continuum (BIC) appears in parametric space. This pape…
Metasurfaces with bound states in the continuum enabled by eliminating first Fourier harmonic component in lattice parameters
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
Conventional photonic lattices, such as metamaterials and photonic crystals, exhibit various interesting physical properties that are attributed to periodic modulations in lattice…
