“Holographic generation of an electron Airy beam. An electron beam is transmitted through a nanofabricated hologram, with a cubic phase modulation. It is then focused by a magnetic lens. The Airy wave packet is formed at the back focal plane and recorded as it propagates. The electron Airy beam is a shape-preserving beam that evolves along a curved trajectory. It also self-heals after encountering obstacles.” Via.
