Terahertz time-domain spectroscopy (THz-TDS) is a powerful technique for material's
characterization and process control. It has been used for contact-free conductivity …

Active plasmonics is a burgeoning and challenging subfield of plasmonics. It exploits the
active control of surface plasmon resonance. In this review, a first-ever in-depth description …

Terahertz (THz) radiation encompasses a wide spectral range within the electromagnetic
spectrum that extends from microwaves to the far infrared (100 GHz–∼ 30 THz). Within its …

We present an overview of the main techniques for production and processing of graphene
and related materials (GRMs), as well as the key characterization procedures. We adopt …

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 …

In this paper we present the efficient design of functional thin-film metamaterial devices with
the effective surface conductivity approach. As an example, we demonstrate a graphene …

We have measured the terahertz frequency-dependent sheet conductivity and its transient
response following femtosecond optical excitation for single-layer graphene samples grown …

We demonstrate the excitation and gate control of highly confined surface plasmon
polaritons propagating through monolayer graphene using a silicon diffractive grating. The …

Gate-controllable transmission of terahertz (THz) radiation makes graphene a promising
material for making high-speed THz wave modulators. However, to date, graphene-based …
