the years, the basic idea remains the same: Each cone comprises an ultra-thin layer of aluminum foil (six one-thousandth of a millimeter thick in the tweeter), a layer of hard foam, and a tissue-like backing of paper. As the foam is 85% air, the entire “sandwich” is featherweight...
Signal strength in millimeter-wave and terahertz fixed wireless systems can be strongly affected by severe weather conditions, such as attenuation due to heavy rain and antenna vibration due to wind. The results from a field trial experiment were compared with relevant models, which could be used ...
The millimeter size coupled with a negative surface charge of the beads are shown to be critical in order to achieve high levels of concentration. This new concentration procedure is very fast, effective, scalable, and low-cost with no need for complex instrumentation. 展开 ...
