jun 14, 2021 smooth copper is the solution to this problem but costs more. the signal is following every crest and trough based on the surface profile, adding to path length and resistance leading to attenuation. resistance of ground return path as frequency increases, the ground return path becomes narrow and uses less copper area, resulting in increased
take the material of the screw-lift copper nut as an example. the material is generally lead brass. at present, most of the copper nuts sold in the market are copper alloys, and pure copper is rarely used as copper nuts. the advantage of using alloy copper nuts is that they can make up for the shortcomings of copper
sep 24, 2021 radiation shielding is based on the principle of attenuation, which is the ability to reduce a waves or rays effect by blocking or bouncing particles through a barrier material. charged particles may be attenuated by losing energy to reactions with electrons in the barrier, while x-ray and gamma radiation are attenuated through
