Terahertz detectors could also be used for airport security to detect illicit drugs hidden in peoples clothes. The approach is less invasive than X-rays, said Liu, since terahertz waves are much less energy.

He trusts me, this figure is probably just something to do with issues of water and metal, too. I think there are puddles in the Middle East, yeah! Skepticism aside, it is certainly very, very clever solution to the limited scope of terahertz waves. Have not we from them? It should also be defeated by a pool of water that ran over a sufficient depth to cover foreign direct investment. Therefore, FDI can see a little, but will not be able to distinguish the difference between that and a little tin buried? Is it really better? I guess IEDs are usually placed in metal or container of some sort, in order to use this thing for the detection of FDI do not seem to get more than a metal detector can provide the long term.
