does not perform equally well in all directions. A common way to characterize the performance of an antenna is the radiation pattern, which is a graphical representation of the radiation properties of an antenna as a function of space coordinates. The simplest pattern is produced by an idealized...
In December 17th, CCTV "Truth Investigation" reporter conducted experiments on the radiation protection clothing that was publicized to prevent 99.9% radiation. It was found that radiation protection clothing could block 90% of radiation under the condition of one radiation source. However, the radiati...
