From Terahertz Imaging to Terahertz Wireless Communications
Engineering, 2022 Terahertz (THz) technology is probably best known to the public as a powerful tool for imaging, since it has been applied in security and medical scanning, resulting in numerous impressive images that would be unobtainable using other technologies. With the roll-out of 5G mobile networks, research into 6G wireless communications is heating up.

Ultrafast terahertz magnetometry [PDF]
Nature Communications, 2020 AbstractA material’s magnetic state and its dynamics are of great fundamental research interest and are also at the core of a wide plethora of modern technologies. However, reliable access to magnetization dynamics in materials and devices on the technologically relevant ultrafast timescale, and under realistic device-operation conditions, remains a ...

Optics Express, 2012 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 [PDF]
PIERS Online, 2010 Development of millimeter and sub-millimeter wavelengths technologies is of great interest lately, especially for application in so called terahertz imaging. As a rule, two main approaches are used for this purpose based on employment of active and passive methods of visualization.

Experimental investigation of optically controlled topological transition in bismuth-mica structure
Scientific Reports, 2021 The hyperbolic materials are strongly anisotropic media with a permittivity/permeability tensor having diagonal components of different sign. They combine the properties of dielectric and metal-like media and are described with hyperbolic isofrequency ...

Optics Letters, 2018 We realized a phase retrieval technique using terahertz (THz) radiation as an alternative to THz digital holography, named THz ptychography. Ptychography has been used in x-ray imaging as a groundbreaking improvement of conventional coherent diffraction imaging. Here we show that ptychography can be performed at THz frequencies too. We reconstructed an
