Abstract: Abstract In this paper, a 3D ellipsoidal lens is designed based on the transformation optics (TO) method. The conventional Luneburg and Gutman lenses are mapped to an ellipsoidal lens to make a fan-beam radiation pattern.… read more here.

Abstract: In a combined theoretical and experimental study, we give evidence that the self-organized electric potential in tapered glass capillaries has the strength to focus a low-energy ion beam. Similar to Einzel lenses, the on-axis injected… read more here.
