TeraHertz: New opportunities for industry

TeraView are happy to confirm that Dr. Philip Taday will be speaking at the upcoming event: TeraHertz: New opportunities for industry - Special Focus Session: THz Materials Measurements, on the 3rd-5th of February 2015.

Event Overview:

TeraHertz (THz), the frequencies between electronics and optics, was until recently the last unexploited part of the electromagnetic spectrum. The harnessing of THz-based technologies has the potential of impacting globally a vast number of industries, like both electronics in the 70’s and optics in the 80’s did. THz applications span over a wide array of fields, including:

• Quality Control and Non-destructive testing
• Surface analysis
• Security
• Chemical and Bio-Medical analysis
• Telecommunications

Filling the TeraHertz “gap” has led to unprecedented creativity in the development and commercialization of TeraHertz sources, transmission components and detectors. This year’s edition will focus on THz materials measurements and applications.

THz structures fabricated in laser direct patterning

Koziol, P.E. ; Antonczak, A.J. ; Walczakowski, M. ; Palka, N. 


In this paper two different methods of the manufacture of metamaterial structures using a laser treatment were presented. One of them is related to direct metallization of the surface of aluminum nitride ceramics (AlN) by interaction of laser radiation. The second method involves a process of selective removal of the conductive layer (silver) in the laser ablation process. It has been proved that both proposed methods allow to produce a structure of SRR type showing its properties in THz range. Obtained results allow to implement these methods for the manufacture of more complex structures. An advantage of the process of laser radiation interaction on the surface of a material is the ability to produce any shape without having to adapt further process components.

Flat THz leaky wave antennas: Analysis and experimental results

Beaskoetxea, Unai ; Beruete, Miguel ; Zehar, Mokhtar ; Agrawal, Amit 


Here, two different THz radiating structures are analyzed, consisting both of a central slot surrounded by annular or straight corrugations. Concentrically grooved antenna presents a moderately high gain. Its radiation and temporal properties are analyzed both numerically and experimentally. For the second case, no appreciable differences in terms of radiation characteristics are observed when the grooves' profile is changed from square to triangular. Manufactured triangular grooves antenna shows good performance for the experimental measurements at 0.5THz. These results could be of interest for the development of new THz sources and detectors.

Wavelet denoising and reconstruction of a microneedle embedded in human skin ex-vivo using terahertz pulsed reflectance

Mueller-Holtz, Martin ; Smith, Geoff


Biological tissue can show promising features in the terahertz region of the electro-magnetic spectrum but face the problem that the signal to noise ratio can be poor due to the low energy output from the measurement instrument coupled with the high absorbance of water in biological tissue. Wavelet denoising and reconstruction are known to be suitable digital signal processing filters for reflected terahertz energy when appropriate thresholds, scales and mother-wavelets are chosen. In this article, we therefore describe a Wavelet transform-based method for denoising reflections of THz energy from ex-vivo human skin with an embedded microneedle. The wavelet reconstruction was then successfully used to identify the microneedle from the reflected waveform. This technique is potentially useful to enhance in-depth analysis and visualisation of underlying skin layers, lesions and penetration depth for targeted drug delivery.
