A system of two probes is designed for terahertz (THz) time-domain spectroscopy of sub-
wavelength size objects. A twin-needle probe confines broadband THz pulses spatially by …

We present a terahertz time-domain spectroscopy system having the capability to vary the
angle between the detector and sample location over a range of 0 to 360. Terahertz (THz) …

We present a low cost terahertz (THz) spectrometer with coherent detection based on two
simple and robust dipole antennas driven by two laser diodes. The spectrometer covers …

Terahertz science and technology are progressing at a tremendous speed as evidenced by
the ever increasing numbers of publications in this field. The field is becoming large enough …

We report on a method to obtain a subwavelength resolution in terahertz time-domain
imaging. In our method, a sharp copper tip is used to locally distort and concentrate the THz …

We present terahertz (THz) time-domain spectroscopy (TDS) as a versatile tool for
applications in non-destructive testing. Due to fiber-coupled THz systems, which exploit the …

Terahertz (THz) systems open up the possibility of new applications of electromagnetic
waves. Enormous bandwidths up to several terahertz enable the development of powerful …

A compact and rigid terahertz time domain spectroscopy system is presented. The size of the
device is 20 mm diameter times 61 mm length with four parabolic-shaped concave mirrors …

We demonstrate terahertz (THz) imaging with a quasi-time-domain spectrometer. This type
of THz system is inexpensive, compact, and relatively easy to set up. Beating the …

Transmission of single-cycle terahertz pulses through subwavelength apertures is
experimentally studied in the near-field zone. Measurements of throughput for aperture sizes …
