First Instance Of Negative Effects From Terahertz-Range Electromagnetic Waves
2014-06-20 12:44:04| rfglobalnet Home Page
Electromagnetic waves (EM-wave) in the terahertz range were widely regarded as the “dream wavelength” due to its perceived neutrality. Its application was also wider than X-rays. However, KAIST scientists have discovered negative effects from terahertz EM-waves.
