Bibliometric data set the scene by illustrating the growth of terahertz work and the present
interest in terahertz science and technology. After locating terahertz sources within the …

Over the past three decades a new spectroscopic technique with unique possibilities has
emerged. Based on coherent and time‐resolved detection of the electric field of ultrashort …

We review pioneering and recent studies of the conductivity of solid state systems at
terahertz frequencies. A variety of theoretical formalisms that describe the terahertz …

Terahertz (THz) spectroscopy, and especially THz imaging, holds large potential in the field
of nondestructive, contact-free testing. The ongoing advances in the development of THz …

Terahertz frequency radiation possesses a unique combination of desirable properties for
noninvasive imaging and spectroscopy of materials. This includes the ability to obtain …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

The photo-Dember effect is a source of impulsive THz emission following femtosecond
pulsed optical excitation. This emission results from the ultrafast spatial separation of …

The photo-Dember effect is a source of pulsed THz emission following femtosecond pulsed
optical excitation. The emission results from the ultrafast spatial separation of electron–hole …

In this paper, we review the past and recent works on generating intense terahertz (THz)
pulses from photoconductive antennas (PCAs). We will focus on two types of large-aperture …

We have generated coherent pulses of terahertz radiation from macroscopic arrays of
aligned single-wall carbon nanotubes (SWCNTs) excited by femtosecond optical pulses …
