According to its useful properties (listed below) that can be applied to the application, for example, healthcare, security or imaging applications. - lower photon energy than x-rays – due to the higher wavelength, hence the energy is lower. Therefore, the possibility of the ionization is low meaning that the T-rays (Terahertz rays) is safe for users and operators, - extreme water absorption – the terahertz frequency cannot pass through any kind of water molecule including the vapor meaning that T-rays will be blocked from the vapor in the air. So the wave can propagate only in the meter range distance, - longer wavelength than visible and IR – meaning that the T-rays will have less affected by Mie Scattering, so the wave can penetrate through almost drying dielectric materials.
