Chemical and physical systems undergoing change display spectral signatures from the
radio frequency to the X-ray region of the electromagnetic spectrum. This has led to the …

Organic π‐conjugated crystals with second‐order optical nonlinearity are considerably
attractive materials for diverse terahertz (THz) wave photonics. An overview of the research …

The ultrafast relaxation and recombination dynamics of photogenerated electrons and holes
in epitaxial graphene are studied using optical-pump terahertz-probe spectroscopy. The …

We discuss the use of terahertz time domain spectroscopy for studies of conformational
flexibility and conformational change in biomolecules. Protein structural dynamics are vital to …

Terahertz radiation from InSb and InAS, which are typical narrow band-gap semiconductors,
was investigated using time-resolved THz emission measurements. When we compared …

In this paper techniques for the generation and measurement of ultrashort pulses in the
frequency range from about 0.1 to 10 THz are reviewed. The methods for generation are …

Terahertz (THz) science will profoundly impact biotechnology. It has tremendous potential
for applications in imaging, medical diagnosis, health monitoring, environmental control and …

Polarization sha** of terahertz pulses enables us to manipulate the temporal evolution of
the amplitude and direction of electric-field vectors in a prescribed manner. Such arbitrary …

We present a detailed experimental and theoretical study of terahertz (THz) generation and
beam propagation in an optoelectronic THz system consisting of a large-area (ZnTe) electro …

We have performed high-precision terahertz time-domain spectroscopy measurements on
polymers (cross-linked polystyrene, TPX, Zeonor) from 0.2 to 4.2 THz. They show very …
