Gain-controlled directional scattering in core-shell nanoparticles mediated by magnetic toroidal dipoles
Tiago J. Arruda
Toroidal dipole moments arise from poloidal current distributions and form a distinct class of electromagnetic excitations with unique near-field characteristics. Using Lorenz-Mie…

Electric and magnetic toroidal dipole excitations in core-shell spheres
Tiago José Arruda
Toroidal dipole moments, which consist of enclosed circulating currents aligned along paths within a torus shape, can be experimentally achieved in metamaterials using various geom…
