Superscattering Empowered by Bound States in the Continuum
Adrià Canós Valero, Hadi. K Shamkhi, Anton S. Kupriianov +6
We uncover a novel mechanism for superscattering of subwavelength resonators closely associated with the physics of bound states in the continuum. We demonstrate that superscatteri…
Multimode parity-time and loss-compensation symmetries in coupled waveguides with loss and gain
Anton V. Hlushchenko, Vitalii I. Shcherbinin, Denis V. Novitsky +1
Loss compensation via inserting gain is of fundamental importance in different branches of photonics, nanoplasmonics, and metamaterial science. This effect has found an impressive…
Toroidic and antitoroidic orders in hexagonal arrays of dielectric trimers: magnetic group approach
Victor Dmitriev, Silvio Domingos Silva Santos, Andrey B. Evlyukhin +2
Herein, we investigate the symmetry-protected toroidal dipole resonances and conditions of their excitation in a new type of electromagnetic metamaterials. These metamaterials are…
Loss compensation symmetry of unequally sized dielectric cylinders with gain and loss
Anton V. Hlushchenko, Vitalii I. Shcherbinin, Denis V. Novitsky +1
A rigorous analytical approach is applied to solve the eigenvalue problem for a pair of circular dielectric cylinders with complex permittivity. This approach relies on field expan…
Invisibility and perfect absorption of all-dielectric metasurfaces originated from the transverse Kerker effect
Hadi K. Shamkhi, Andrey Sayanskiy, Adria Canos Valero +5
Dielectric metasurfaces perform unique photonics effects and serve as the engine of nowadays light-matter technologies. Here, we suggest theoretically and demonstrate experimentall…
Dual-polarized all-angle cloaking of a dielectric nanowire by helical graphene ribbons
Vitalii I. Shcherbinin, Yuliya K. Moskvitina, Volodymyr I. Fesenko +1
Scattering from a dielectric nanowire coated by helical graphene strips (nanoribbons) is investigated for dual-polarized wave at oblique incidence. In the long-wavelength approxima…
