Low-loss polymers for terahertz applications
Applied Optics, 2008We have performed high-precision terahertz time-domain spectroscopy measurements on polymers (cross-linked polystyrene, TPX, Zeonor) from 0.2 to 4.2 THz. They show very interesting terahertz and visible transparency. We also investigated the terahertz characteristics of PDMS, a polymer extensively used in microfluidics, which showed absorption ...

Terahertz Spectroscopy and Applications
2006 IEEE International Frequency Control Symposium and Exposition, 2006There has been a long and intimate relationship between frequency measurement and spectroscopy. For a time, wavelength based optical measurements and frequency based microwave measurements provided a measure of the speed of light. While as fundamental references these have been eclipsed by exquisite modern atomic measurements, frequency measurement and

Terahertz Applications to Biomolecular Sensing
International Journal of High Speed Electronics and Systems, 2003THz time domain spectroscopy of biomolecules was performed to determine applicability of the technique for chemical and conformational identification of biomolecules. Measurements were performed on samples of DNA, bovine serum albumin, collagen, hen egg white lysozyme, myoglobin, and bacteriorhodopsin as a function of temperature, hydration and ...

Bolometric Receivers for Terahertz Applications
SPIE Proceedings, 2003Bolometric receivers serve as direct detectors, photon counters and as heterodyne receivers in astronomical instruments. Heterodyne hot-electron bolometric mixers show record sensitivity for observation frequencies above a Terahertz. In this paper NbN phonon-cooled mixers, conversion gain, noise and stability are discussed based on device models ...

Security applications of terahertz technology
SPIE Proceedings, 2003Recent events have accelerated the quest for ever more effective security screening to detect an increasing variety of threats. Many techniques employing different parts of the electromagnetic spectrum from radio up to X- and gammaray are in use. Terahertz radiation, which lies between microwave and infrared, is the last part to be exploited for want,

Terahertz Applications Inspired by Photonics
2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2018This paper discusses how photonics technologies can be efficiently utilized in terahertz (THz) applications, by showing some of our recent results. First, an information tag, which is attached to the object for identification, is designed and fabricated using a THz photonic crystal slab. By storing information in both frequency and spatial domains, the

Spacecraft Applications of Terahertz Technology
1997The terahertz band offers exciting opportunities [1,2,3] for the remote sensing from space of atmospheric constituents with great importance for the planning of industrial and commercial activities. To exploit these opportunities requires the development of new sensor devices combining robustness with decreased dimensions and many developments of ...
