Generation of electromagnetic doughnut pulses with a singular metamaterial converter
Generation of electromagnetic doughnut pulses with a singular metamaterial converter
We present the first experimental demonstration on the generation of “Flying Doughnuts”, space-time inseparable toroidal electromagnetic excitations, by converting ultrashort transverse optical pulses in a singular metamaterial converter. Unique properties of toroidal pulses are discussed.

Abstract
We present the first experimental demonstration on the generation of “Flying Doughnuts”, space-time inseparable toroidal electromagnetic excitations, by converting ultrashort transverse optical pulses in a singular metamaterial converter. Unique properties of toroidal pulses are discussed.
