A bounded source cannot emit a unipolar electromagnetic wave

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/83433We show that a bounded source cannot produce a unipolar electromagnetic pulse. As a consequence, there are no three-dimensional electromagnetic solitons in vacuum.v2 adds one reference: thanks to Evgueni BessonovClassical PhysicsA bounded source cannot emit a unipolar electromagnetic wavetext
