In 2015, North America is expected to account for the largest share of the global terahertz and infrared spectroscopy market, followed by Europe, Asia-Pacific, and the Rest of the World (RoW).

The company also focuses on R&D for emerging markets that benefit from advancements in nanotech and terahertz technologies, and has introduced multi-vision metrology scanning electron microscopes essential to photomask manufacturing, as well as groundbreaking 3D imaging and analysis tools.

For coatings, the crystallinity, constituents, thickness, density, and internal structure can be determined nondestructively by analyzing the time delay and amplitude of terahertz wave pulses reflected by different coating layers with different refractive indices.

But terahertz reflectometry is useful for more than analyzing paint, Rahman added.

"Although it is possible to build large instruments that generate powerful beams of terahertz radiation, these instruments are only useful for a limited set of applications," said Edmund Linfield, Professor of Terahertz Electronics in the University's School of Electronic and Electrical Engineering.

Therefore, in this paper, in terahertz wave frequency band, the electron density is assumed to be on the order of [10.sup.20] -[10.sup.24] [m.sup.-3].

He and Andy Wilson, a principal, researcher at Microsoft Research, have demonstrated several, possible tag designs as well, as the terahertz imaging and data processing steps necessary to read them.

Measurements for the designed HSM samples are performed in Terahertz Time-Domain Spectroscopy (THz-TDS) at room temperature in a dry nitrogen atmosphere.

Operating at telecom wavelengths (that is, the range commonly used in fiber-optic communications), the new device is scalable from near-infrared to terahertz wavelengths and simple to manufacture.

A team at University of Texas at Dallas tuned a small, inexpensive microchip to discern a 'terahertz' band of the electromagnetic spectrum.

Terahertz radiation typically occupies the electromagnetic spectrum between 0.1 THz to 10THz (1 THz = [10.sup.12] Hz), and has widespread biomedical application involving the interaction of terahertz pulse with biological media [1-4].

A number of emerging technologies, including millimeter and terahertz waves, have entered the commercial space, helping to address challenges to passenger screening at airports.
