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…
Equivalent sources approach for non radiating states and anapole metamaterials
Giuseppe Labate, Anar K. Ospanova, Nikita A. Nemkov +2
In this work, we discuss theoretical findings on the common feature describing nonradiating sources, based on equivalent sources from which it is possible to derive cloaking device…
Electromagnetic sources beyond common multipoles
Nikita A. Nemkov, Alexey A. Basharin, Vassily A. Fedotov
The complete dynamic multipole expansion of electromagnetic sources contains more types of multipole terms than it is conventionally perceived. The toroidal multipoles are one of t…
Anapole mode excitation in novel perforated all-dielectric metamaterials
Anar K. Ospanova, Ivan V. Stenishchev, Alexey A. Basharin
In this paper, we concern on nonradiating properties of novel silicon metamaterials due to multipolar interaction. Destructive interference of electric dipole moment and the next t…
Electromagnetically Induced Transparency in all-dielectric metamaterials due to nullifying of multipole moments
Anar K. Ospanova, Alina Karabchevsky, Alexey A. Basharin
Here, we propose novel transparency effect in cylindrical all-dielectric metamaterials. We show that cancellation of multipole moments of the same kind lead to almost zero radiatio…
Blueshift and Phase tunability in planar metamaterials with toroidal contribution
Maria V. Cojocari, Kristina Schegoleva, Alexey A. Basharin
We propose a model of tunable THz metamaterials. The main advantage is the blueshift of resonance and phase tunability due to toroidal excitation in planar metallic metamolecules w…
