T-matrix representation of optical scattering response: Suggestion for a data format
Nigar Asadova, Karim Achouri, Kristian Arjas +43
The transition matrix, frequently abbreviated as T-matrix, contains the complete information in a linear approximation of how a spatially localized object scatters an incident fiel…
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…
Anti-aliased metasurfaces beyond the Nyquist limit
Seokwoo Kim, Joohoon Kim, Kyungtae Kim +2
Sampling is a pivotal element in the design of metasurfaces, enabling a broad spectrum of applications. Despite its flexibility, sampling can result in reduced efficiency and unint…
