Rayleigh Bound States in the Continuum
Ilya Karavaev, Mingzhao Song, Andrey Bogdanov
We predict a class of bound states in the continuum (BICs) in non-subwavelength periodic metasurfaces -- Rayleigh BICs -- that emerge precisely at Rayleigh anomalies, where diffrac…

Optical Resonances: From Eigenmodes to Scattering Features
Ilya Karavaev, Kirill Koshelev, Andrey Bogdanov
Electromagnetic resonances play a central role in nanophotonics by enabling efficient confinement of electromagnetic energy and enhanced light-matter interaction. Traditionally, re…
