Robustness of bound states in the continuum in metasurface based on GeSbTe versus structural imperfections
Nikolai A. Vlasov, Alexander I. Solomonov, Zarina F. Kondratenko +3
We study the impact of lithography imperfections on quasi-bound states in the continuum (quasi-BICs) supported by a one-dimensional metasurface of GeSbTe (GST) bars wit…

Robustness of Bound States in the Continuum in Bilayer Structures against Symmetry Breaking
Kliment V. Semushev, Zilong Zhao, Alexey Proskurin +5
We investigate the robustness of bound states in the continuum (BICs) in a bilayer dielectric rod array against geometric and material perturbations. Our analysis focuses on both s…
