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…
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…
Superscattering from subwavelength corrugated cylinders
Vitalii I. Shcherbinin, Volodymyr I. Fesenko, Tetiana I. Tkachova +1
Wave scattering from a cylinder with a tensor impedance surface is investigated based on the Lorentz-Mie theory. A practical example of such a cylinder is a subwavelength metallic…
Chiral metasurface formed by 3D-printed square helices: A flexible tool to manipulate wave polarization
Shengzhe Wu, Vladimir V. Yachin, Vitalii I. Shcherbinin +1
The transmission of linearly and circularly polarized waves are studied both theoretically and experimentally for chiral metasurfaces formed by arrays of metallic square helices. T…
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…
Multiple invisibility regions induced by symmetry breaking in a trimer of subwavelength graphene-coated nanowires
Volodymyr I. Fesenko, Vitalii I. Shcherbinin, Vladimir R. Tuz
Electromagnetic response is studied for clusters of subwavelength graphene-coated nanowires illuminated by a linearly polarized plane wave in the terahertz frequency range. The sol…
