Tunable bound states in the continuum through hybridization of 1D and 2D metasurfaces
Fedor Kovalev, Mariusz Martyniuk, Andrey Miroshnichenko +1
This work presents a novel approach to create and dynamically control quasi-Bound States in the Continuum (BIC) resonances through the hybridization of 1D and 2D metasurfaces using…

Parametric metasurfaces for amplified up-conversion of electromagnetic waves
Fedor V. Kovalev, Ilya V. Shadrivov
Spatiotemporal metasurfaces, characterized by dynamic variations in both space and time, enable functionalities unattainable with passive metasurfaces. In this study, we propose a…

Active Control of Bound States in the Continuum in Toroidal Metasurfaces
Fedor V. Kovalev, Andrey E. Miroshnichenko, Alexey A. Basharin +2
The remarkable properties of toroidal metasurfaces, featuring ultrahigh-Q bound states in the continuum (BIC) resonances and nonradiating anapole modes, have garnered significant a…
