A Topologically Robust Formation of Broadband Vortices Propagating at the Speed of Light

Not Accessible

Your library or personal account may give you access


We show that Flying Doughnuts, the exact propagating solutions of Maxwell equations in the form of single-cycle toroidal pulses have complex and robust fine topological structure of spectrally broadband vortices and extended areas of energy backflow.
