Terahertz spin current

WebSpin packs are used in the production of synthetic fibers and nonwovens. The spin pack itself is a metal block and consists of cavities and fine channels inside, through which polymer melt – i.e. molten plastic – flows. This melt is fed into the spin pack through a tube. In a first cavity (a hollow space), the melt is distributed over the ... WebA uniform illumination over a screen is crucial for terahertz imaging. As such, conversion from a Gaussian beam to a flattop beam becomes necessary. Most of the current beam …
