Terahertz (THz) research has received much attention recently. This development is due to the discovery of new THz-radiation sources and detectors such as quantum cascade lasers, photoconductive switches or electro-optic THz- detectors during the last decade. Of particular intereset are broadband Thz-spectroscopy and imaging systems operating in the frequency range 0.1-10THz.
This paper describes a technique for imaging in the terahertz regime using time reversal of single cycle pulses. Specifically, the time-reversal symmetry of Maxwell s wa ....etc

terahertz imaging seminar report

Terahertz imaging is an emerging and significant nondestructive evaluation (NDE) technique used for dielectric (nonconducting, i.e., an insulator) materials analysis and quality control in the pharmaceutical, biomedical, security, materials characterization, and aerospace industries.It has proved to be effective in the inspection of layers in paints and coatings,detecting structural defects in ceramic and composite materials and imaging the physical structure of paintings and manuscripts. The use of THz waves ....etc

Abstract

Recently, terahertz (THz) technology has attracted a great deal of interest from academia and industry. This is due to a number of interesting features of THz waves, including the tens and hundreds of gigahertz bandwidths available, and the fact that this frequency band poses only a minor health threat. Also, as millimeter-wave communication systems mature, the focus of research is, naturally, moving to the THz range. According to Shannon theory, the broad bandwidth of the THz fre ....etc

Terahertz Radiation
In physics, terahertz radiation refers to electromagnetic waves sent at frequencies in the terahertz range. It is also referred to as submillimeter radiation, terahertz waves, terahertz light, T-rays, T-light, T-lux and THz. The term is normally used for the region of the electromagnetic spectrum between 300 gigahertz (3x1011 Hz) and 3 terahertz (3x1012 Hz), corresponding to the submillimeter wavelength range between 1 millimeter (high-frequency edge of the microwave band) and 100 micrometer (long-wavelength edge of far-inf ....etc

Imaging technology has a rich history that began thousands of years ago. The reflection from a pool of still water or a shiny metal surface was arguably the first imaging method routinely used by mankind. With the advent of lenses, many other novel forms of optical imaging emerged, including telescopes and microscopes.

Using a lens, a pinhole camera, and a sensitized pewter plate, Ni?pce was the first person to permanently record an image. Optical photography and other forms of optical imaging have since become commonplace.

Of course, im ....etc

MOS transistor is the building block of integrated circuits, and is the engine that powers them. Today?s most complex ICs, such as microprocessors, graphics, and DSP chips, pack more than 100 million MOS transistors on a single chip. Integration of one billion transistors into a single chip will become a reality before 2010.

The semiconductor industry faces an environment that includes increasing chip complexity, continued cost pressures, increasing environmental regulations, and growing concern about energy consumption. New materials an ....etc
