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…
Extremely High Q-factor metamaterials due to Anapole Excitation
Alexey A. Basharin, Vitaly Chuguevsky, Nikita Volsky +2
We demonstrate that ideal anapole metamaterials have infinite Q-factor. We have designed and fabricated a metamaterial consisting of planar metamolecules which exhibit anapole beha…
Extremely high Q-factor toroidal metamaterials
Alexey A. Basharin, Vitaliy Chuguevskiy, Nikita Volsky +3
We demonstrate that, owing to the unique topology of the toroidal dipolar mode, its electric/magnetic field can be spatially confined within subwavelength, externally accessible re…
