Terahertz Technology utilizes terahertz waves which oscillate at 12th power of 10 times per second. Terahertz waves have longer wavelengths compared to visual rays or infrared allowing better transmittance and shorter wavelengths compared to microwaves which allow utilizations in high resolution image systems.

The technology has become an active research topic among leading countries for communication, military, and industrial applications.

Research on terahertz signal source generation and radio detection technologies are being conducted. The goal is to acquire high-speed/high-capacity communication technology and all-weather surveillance technology, both expected to be required in future battlefields.
