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 terabit wireless communication ppt download

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

carbon nanotube antenna in the sub terahertz range ppt

Abstract

In this paper, a new antenna configuration is proposed to operate efficiently in the sub-terahertz frequency range (10-1000 GHz). The proposed antenna is composed of a bundle of single-walled carbon nanotubes (SWCNTs) surrounded by two dielectric jackets; the inner of which is dielectric foam with relative permittivity close to unity. The outer one is a metamaterial layer with permittivity much smaller than the free-space permittivity. Rigorous analysis shows that the metamateria ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....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

Infrared thermography (IRT), thermal imaging, and thermal video are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000 14,000 nanometers or 9 14 m) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The am ....etc
