Plasma Lens with a Current Density Depended on External
... As a result, if the current density is homogeneous in the electron emitter region, so it will be homogeneous in any other current channel cross-section. It is necessary (and, as a rule, sufficiently) for a good ion focusing without spherical aberration. The equation of the focusing ions trajectories ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
