Current terahertz (THz) spectroscopy techniques only use the coherent light beam for
spectral imaging. In the presence of electromagnetic scattering, however, the scattering …

Terahertz (THz) imaging can serve as a versatile instrument to disclose contents of various
packages or discriminate its constituents. Particular attention deserves a case when …

In this work, we take aim at the fundamental challenge for realizations of broadband
terahertz (THz) spectroscopy on a subwavelength scale. We introduce apertured THz …

The scattering of terahertz radiation from the granular nature of a sample can potentially
distort or obscure its characteristic spectral features. Several techniques have been …

Label-free imaging technology is highly desirable for various bioengineering, medicine, and
chemistry applications. Most existing optical imaging techniques require labeling of the …

Terahertz (THz) imaging is a widely used technique in the study and detection of many
chemicals and biomolecules in polycrystalline form because the spectral absorption …

We present the development and implementation of a novel wavelet shrinkage technique for
the retrieval of obscured characteristic resonant signatures in the scattered terahertz (THz) …

For imaging applications involving biological subjects, the strong attenuation of terahertz
radiation by water means that terahertz pulsed imaging is most likely to be successfully …

We systematically investigate the data analysis methods in terahertz frequency domain
spectroscopy (THz-FDS) with coherent detection. We demonstrate that the Hilbert transform …

Turbid media, made of wavelength-scale inhomogeneous particles, can give rise to many
significant imaging and spectroscopy challenges. The random variation of the refractive …
