From experiments result, the electromagnetic absorption is better because the copper wire gauge is better, the smaller the copper wire gauge, poor absorption due to the tension Ambassador voids cause multiple reflection With different place found that the more number of carbon fibers, conductive is better, so electromagnetic waves is good.
