Abstract

In the present work, we report on resolution enhancement of a terahertz imaging system using the terajet effect. A wavelength-scaled particle (a Te on cube for simplicity) was used to localize incident radiation to a subwavelength volume and focus it directly onto the objects under imaging. A strained-silicon modulation field effect transistor was used as a direct detector of an incident terahertz beam at 0.3 THz. At first, the terahertz imaging of the objects was performed without the cube. A clear enhancement of the resolution of the terahertz image was obtained when the cube was placed in the focal point of the terahertz beam in front of the object of interest.
