Dyakonov-like surface waves in anisotropic cylindrical waveguides
K. Yu. Golenitskii, A. A. Bogdanov
Dyakonov surface waves are a well-known example of surface electromagnetic waves propagating along a plane interface between isotropic and anisotropic dielectric media. Here, we in…
Individual nanoantennas empowered by bound states in the continuum for nonlinear photonics
Kirill Koshelev, Sergey Kruk, Elizaveta Melik-Gaykazyan +4
Bound states in the continuum (BICs) represent localized modes with energies embedded in the continuous spectrum of radiating waves. BICs were discovered initially as a mathematica…
Multipolar origin of bound states in the continuum
Zarina Sadrieva, Kristina Frizyuk, Mihail Petrov +2
Metasurfaces based on resonant subwavelength photonic structures enable novel ways of wavefront control and light focusing, underpinning a new generation of flat-optics devices. Re…
Nonradiating Photonics with Resonant Dielectric Nanostructures
Kirill Koshelev, Gael Favraud, Andrey Bogdanov +2
Nonradiating sources of energy have traditionally been studied in quantum mechanics and astrophysics, while receiving a very little attention in the photonics community. This situa…
