Non-trivial non-radiating excitations and ultra-narrow resonances in toroidal metamaterials

Non-trivial non-radiating excitations and ultra-narrow resonances in toroidal metamaterials
We demonstrate theoretically and confirm experimentally a new mechanism of resonant electromagnetic transparency, which yields narrow isolated symmetric Lorentzian transmission lines in metamaterials. It exploits the long sought non-trivial non-radiating charge-current excitation based on interfering electric and toroidal dipole moments.

Abstract

We demonstrate theoretically and confirm experimentally a new mechanism of resonant electromagnetic transparency, which yields narrow isolated symmetric Lorentzian transmission lines in metamaterials. It exploits the long sought non-trivial non-radiating charge-current excitation based on interfering electric and toroidal dipole moments.
