Polaritonic spectra of optical Mie voids
Evgeny Ryabkov, Mingzhao Song, Andrey A. Bogdanov +1
The progress in understanding the optical and microscopic properties of polaritons relies on various optical cavities to confine electromagnetic radiation, which causes a demand fo…

Robustness of Bound States in the Continuum in Bilayer Structures against Symmetry Breaking
Kliment V. Semushev, Zilong Zhao, Alexey Proskurin +5
We investigate the robustness of bound states in the continuum (BICs) in a bilayer dielectric rod array against geometric and material perturbations. Our analysis focuses on both s…

Temporal coupled mode theory for high- resonances in dielectric metasurfaces
Dmitrii N. Maksimov, Pavel S. Pankin, Dong-Wook Kim +3
In this work, we propose a coupled mode theory for resonant response from quasi-guided modes in periodic dielectric metasurfaces. First, we derived a generic set of constraints imp…
