TeraView at the 'Advances in Terahertz Spectroscopy' meeting held in Cambridge, UK

Last week the 'Advances in Terahertz Spectroscopy' meeting was held at the Gonville and Caius College in Cambridge UK, with the event being jointly hosted by Teranet (an EPSRC-funded network of UK Universities and companies active in terahertz science and technology) and the the Royal Society of Chemistry.  

TeraView brought along its latest product, the TeraPulse 4000.  TeraView is grateful for all of the feedback received, especially the positive comments and suggestions from the hands-on session.

Below are some pictures from the workshop.

If you would like to participate in a hands-on workshop and learn more about terahertz applications and technology please do not hesitate to contact us or sign up for our next workshop in Bordeaux, France. More information on the Bordeaux event can be found here.

Wide angle terahertz sensing with a cross-dipole frequency selective surface

P. Rodríguez-Ulibarri | S. A. Kuznetsov | M. Beruete


In this work, a terahertz sensor based on a cross dipole frequency selective surface is analyzed and experimentally tested. The sensing structure is optimized for operation at the fundamental band-stop resonance near 0.7 THz and characterized under normal and oblique incidence. The sensing performance as a function of the incidence angle and the wave polarization is evaluated with good agreement between simulations and measurements. It is shown that a figure of merit for the proposed sensor can be enhanced from 0.2 up to 0.6 due to switching from normal to oblique excitation, which yields the maximum performance for TM polarization at the incidence angle of 70°. The presented results demonstrate a wide angle operation regime in THz sensing that opens up an alternative approach in improving capabilities of sensing devices.

Terahertz Imaging Platform to Characterize the Growth of In-Vitro Breast Tumors


This study aimed at evaluating the ideal plating method and density for imaging with the terahertz (THz) spectrometer. In this study, different methods were used to grow in-vitro tumors using the 4T1 cell line. Here, attempts to grow breast tumors in-vitro were conducted. Results were produced in two environments, flat-bottomed plates and round-bottomed multiwell plates. The second method allowed for faster clumping and increased cell aggregation, producing tumors up to 7mm. Terahertz spectroscopy produced images that correlated well to photomicrographs taken of the in-vitro tumors. This methodology shows great promise for providing a reliable, parameter-controlled source of in-vitro breast tumors for research needs on breast tumor margins.

Non-destructive evaluation of puncture region in polyethylene composite by terahertz and X-ray radiation

Norbert Palkaa ;  Robert Panowiczb ; Marek Chalimoniukc ; Rene Beigang 

An ultra-high molecular weight polyethylene composite sample has been non-destructively imaged via X-ray and Terahertz waves. The sample stopped a projectile, which resulted in delaminations, a bulge, and a chamber. Although the X-ray computed tomography reliably showed all interesting internal features of the sample, the axial resolution was moderate and artefacts and deformations limited its performance. A terahertz time domain spectroscopy system was used both for transmission and reflection raster scanning of the sample. The propagation of the THz pulse through the sample was compared with a theoretical model. Transmission investigations roughly determined the distribution of delaminations and size of the chamber. The reflection scanning through the time-of-flight analysis and signal processing enabled a detailed 3D imaging of the sample. A very good agreement of X-ray and THz images was achieved. Both measurement methods were compared and discussed.
