The electrons in an EP beam don't behave exactly as predicted by simple models. They perform differently at different ...

Unlike a typical flashlight beam, they do not spread out as they travel. They even have the capability of “self-healing,” meaning that if an obstacle blocks part of the beam, the rest of the beam ...

Optical rotatum” is the term researchers coined to describe a newly discovered structure of light. Beams of light that can be ...

In e-beam lithography, or EBL, shapes are drawn onto a wafer using an electron beam in a vacuum chamber. This is a slow process compared to optical lithography, as used in mass production ...
