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…

Emergence of collective spectral features in finite arrays of dielectric rods
Ilya Karavaev, Ravshanjon Nazarov, Yicheng Li +2
Periodic optical structures, such as diffraction grating and numerous photonic crystals, are one of the staples of modern nanophotonics for the manipulation of electromagnetic radi…
