Terahertz (THz) science and technology have greatly progressed over the past two decades
to a point where the THz region of the electromagnetic spectrum is now a mature research …

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 …

The birth of terahertz imaging approximately coincides with the birth of the journal Optics
Express. The 20^ th anniversary of the journal is therefore an opportune moment to consider …

Terahertz instrumentation has improved significantly in recent years such that THz imaging
systems have become more affordable and easier to use. THz systems can now be operated …

Overview and Scope. THz radiation, with frequencies in the range of 0.1 À20 THz, can probe
physical phenomena such as low-energy excitations and carrier dynamics in electronic …

Interest in biomedical terahertz research is growing rapidly and there are now several
terahertz groups in Asia, Europe and the US investigating potential applications such as …

Terahertz (THz) spectroscopy systems are widely employed to retrieve the chemical and
material composition of a sample. This is single-handedly the most important driving …

Scattering-assisted synthesis of broadband optical pulses is recognized to have a cross-
disciplinary fundamental and application importance. Achieving full-waveform synthesis …

We report a simple single-pixel imaging system with a low mean squared error in the entire
terahertz frequency region (3-13 THz) that employs a thin metallic ring with a series of …

Imaging at terahertz frequencies has recently received considerable attention because
many materials are semitransparent to THz waves. The principal challenge that impedes a …
