Broken-symmetry phenomena enhanced by quasi-bound states in the continuum
Jan David Fischbach, Lukas Rebholz, Nikita Ustimenko +3
Many of the most powerful and elegant models in physics are grounded in symmetries. In electrodynamics, for example, geometric symmetries govern the observable effects of light-mat…

Singular value decomposition to describe bound states in the continuum in periodic metasurfaces
Nikita Ustimenko, Ivan Fernandez-Corbaton, Carsten Rockstuhl
Understanding how bound states in the continuum (BICs) emerge in periodic metasurfaces is essential for the controlled design of high-Q resonances and their systematic manipulation…
