Procedia CIRP. 74:611-617
Ultra-fast lasers have already been used to machine rotational symmetric metallic parts for several years but did not prevail against much cheaper fiber lasers. The limiting factor up to now is the dynamics of the rotary and linear axes, that are use

Building materials attenuate the microwaves used for telecommunication depending on their composition and thickness. Modern windows contain glass with a metallic coating. This might cause a low quality of cell phone reception inside some buildings. I

In order to reduce the energy consumption of buildings, modern windows include metal-containing coatings. These coatings strongly attenuate the microwaves used for mobile communications. Here, we present a novel approach to improve radio signal trans
