THz

Example THz signals from the THz-TDS system are presented in Figure 2 for transmission through both air and analogue tile.

By reducing the overall rod-SRR structural size below 100 [micro]m and structural details down to 5 [micro]m, the frequency at which composite material exhibits the electromagnetic MTM behaviour increased (to few THz).

The AMC unit cell made of graphene sheet is shown in Figure 1(a), and the surface impedance of the patch array at THz band can be approximated by [6,13,14]

There exist four obvious transmission resonant frequencies: [f.sub.1] = 4.8 THz, [f.sub.2] = 5.6 THz, [f.sub.3] = 7.9 THz and [f.sub.4] = 8.2 THz for LCP and RCP waves, respectively.

This approach may be scaled up to low THz operating frequencies with current technology.

Korter's lab is one of only a handful of university-based research labs in the world exploring the potential of THz radiation for chemical and pharmaceutical applications.

The measurement principle for determining coating layer thickness is based on the focusing of a subpicosecond pulse of THz radiation onto the surface of a tablet.

The group, led by Xi-Cheng Zhang, Ph.D., director of the Center for THz Research at Rensselaer, used a system of pulsed lasers to generate a kind of "radar" of waves in the terahertz range.

Daryoosh Saeedkia, who was born in Tehran and raised in Mazandaran, has been the CTO of the system technology development company since 2006; the company specializes in the field of TeraHertz ("THz").
