Bound States-to-Bands in the Continuum in Cylindrical Granular Crystals
Yeongtae Jang, Seokwoo Kim, Dongwoo Lee +2
We theoretically investigate and experimentally demonstrate that genuine bound states in the continuum (BICs) -- polarization-protected BICs -- can be completely localized within f…

Singular Topological Edge States in Locally Resonant Metamaterials
Yeongtae Jang, Seokwoo Kim, Eunho Kim +1
Band topology has emerged as a novel tool for material design across various domains, including photonic and phononic systems, and metamaterials. A prominent model for band topolog…
