The ability to retrieve information from different layers within a stratified sample using terahertz pulsed reflection imaging and spectroscopy has traditionally been resolution limited by the pulse width available. In this paper, a deconvolution algorithm is presented which circumvents this resolution limit, enabling deep sub-wavelength and sub-pulse ...

Subsurface Sub-terahertz and Terahertz Tomography
Development of millimeter and sub-millimeter wavelengths technologies is one of the most promising research areas, especially for applications in so called terahertz imaging. In the paper we consider a tomography approach for obtaining 3-D imaging in frequency range from 100 GHz up to 325 GHz.

Multi-resonant tunable absorber of terahertz metamaterial based on GaAs and VO2
Based on the fact that the conductivity of photosensitive semiconductors can be regulated by external pump light, a metamaterial absorber with single-band and dual-band switchable in terahertz region is designed by replacing gallium arsenide (GaAs ...
