Analytical model of metasurfaces comprising meta-atoms with anisotropic polarizabilities
Izzatjon Allayarov, Vladimir R. Tuz, Antonio Calà Lesina +1
A general analytical approach to the study of electromagnetic resonances of metasurfaces consisting of meta-atoms with anisotropic electric and magnetic dipole polarizabilities and…
Merging high localization and TE-TM polarization degeneracy of guided waves in dielectric metasurfaces
Rui Li, Sergey Polevoy, Vladimir Tuz +1
The polarization degree of freedom is an inherent feature of plane waves propagating in an isotropic homogeneous medium. The miniaturization of optical systems leads to the high lo…
Homogeneous enhancement of electric near-field in all-dielectric metasurfaces composed of cluster-based unit cells
Anton S. Kupriianov, Kateryna L. Domina, Vyacheslav V. Khardikov +2
In order to construct a dielectric analog of spaser, we study theoretically and experimentally several configurations of cluster-based unit cells for an all-dielectric metasurface…
Spontaneous and engineered transformations of topological structures in nonlinear media with gain and loss
B. A. Kochetov, O. G. Chelpanova, V. R. Tuz +1
In contrast to conservative systems, in nonlinear media with gain and loss the dynamics of localized topological structures can exhibit unique features that can be controlled exter…
