Abstract

Terahertz electromagnetic waves are considered the waves for the next generation of security checking technology. They can penetrate opaque materials, such as plastics, fibers, papers, and leathers. In addition, they are harmless to humans they cannot penetrate human skins. Moreover, because their frequencies are higher than those of millimeter waves, higher resolution and more detailed information is expected than the millimeter wave-based technologies In this study, we describe the trends and prospectives of terahertz technology as security checking technology that can be directly applied to a human body.
