FLEET - FLying ElectromagnEtic Toroids
Toroidal electrodynamics has become a key area for our research from 2004 with support from the UK Engineering and Physical Science Research Council grant “Supertoroids Challenge Established Laws of Physics”. It is continued today as the European Research Council Advanced Grant “FLEET: Flying Electromagnetic Toroids”.
Our group claims the following major discoveries in the field of toroidal electrodynamics:
