Phase-Flow Topology of Bound States in the Continuum
Nikolai A. Vlasov, Varvara P. Panurchenko, Ravshanjon Kh. Nazarov +3
Control of topological charges of bound states in the continuum (BICs) is essential for advanced topological photonics. A rigorous theoretical framework for understanding the forma…

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…
