Bound states in the continuum versus material losses: as an example

DV Bochek, NS Solodovchenko, DA Yavsin… - Physical Review B, 2022 - APS
Photonic bound states in the continuum (BIСs) were investigated depending on material and
radiation losses on the example of the phase-change chalcogenide Ge 2 Sb 2 Te 5 and two …
