When the skies come alive: The magic of ice crystal displays
On cold, sunny days, tiny ice crystals in the atmosphere can create breathtaking displays like halos, sundogs, and light pillars.
Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...
For flowering plants, reproduction is a question of the birds and the bees. Attracting the right pollinator can be a matter ...
During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...
Making a perfect lens that produces flawless images has been a dream of lens makers for centuries. In 1873, Ernst Abbe discovered a fundamental 'diffraction limit' in optics: whenever an object is ...
Abstract: Fermat’s Principle, or the Principle of Least Time, is used to computationally model common optical phenomena, including reflection, refraction and dispersion through a prism. Fermat’s ...

Abstract: In this article, we propose a low reflection folded waveguide (LRFWG) as the slow wave structure (SWS) for the development of a terahertz (THz) traveling-wave tube (TWT). Our simulation ...
