Non-Hermitian Singularities in Scattering Spectra of Mie Resonators
Fan Zhang, Nikolay S. Solodovchenko, Hangkai Fan +4
Non-Hermitian systems are known to possess unique singularities in the scattering spectra such as exceptional points, bound states in the continuum, Diabolic points, and anapole st…
Quadruplets of exceptional points and bound states in the continuum in dielectric rings
Nikolay Solodovchenko, Kirill Samusev, Mikhail Limonov
In photonics, most systems are non-Hermitian due to radiation into open space and material losses. At the same time, non-Hermitianity defines a new physics, in particular, it gives…
Optical galleries of dielectric rings: antipode to whispering gallery modes
A. P. Chetverikova, M. S. Sidorenko, K. B. Samusev +2
A general picture of photonic eigenmodes of dielectric rings with a rectangular cross section is presented, which is fundamentally different from those of whispering gallery modes…
Bound states in the continuum in strong-coupling and weak-coupling regimes under the cylinder-ring transition
Nikolay Solodovchenko, Kirill Samusev, Daria Bochek +1
Bound states in the continuum (BIC) have been at the forefront of research in optics and photonics over the past decade. It is of great interest to study the effects associated wit…
