Company Overview

TeraView Ltd is the world’s first and leading provider of Terahertz solutions to Fortune 500 companies, in a variety of industries. TeraView’s advanced portfolio of Terahertz applications knowledge, system design, product range and intellectual property (63 patents granted) is unrivalled in breadth and depth.  There now exists an unprecedented opportunity to exploit this first mover advantage in select, commercially validated markets, to establish a commercially dominant position in this last unconquered region of the electromagnetic spectrum. 

TeraView’s vision is to establish Terahertz as the premier imaging tool for the 21st century, comparable to the enormous success of X-Ray the latter half of the last century, and more recently ultrasound. Ultrasound progressed from research to become an extensively used tool in inspection and other applications, as a result of technological advances similar to those now transforming Terahertz. The current ultrasound market is valued at close to $3.2B per annum, and has an annual growth rate of 30% +.

A Design of Terahertz Broadband Filters and Its Effect in Eliminating Asymmetric Characteristics in Device Structures

Zhu, M. ; Lee, C.


We report a straightforward way to design and fabricate polarization-insensitive broadband bandstop filters in terahertz range by fabricating identical metal patterns on both sides of a dielectric substrate with one layer rotated 90o to the other. The unit cells used in such designs are the well-studied split-ring-resonators, hence the frequency range of the stop band can be easily tuned by varying the dimensions of the unit cell structures. Through simulation analysis, we show that such fabrication method requires no alignment in lithography step and works with common dielectric substrates. Two types of substrates, 1 mm-thick quartz and 100 μm-thick polyethylene terephthalate, were used as a demonstration. The transmission level stayed below 12% for a stopband of 0.42 THz frequency range. Lastly, we reasoned with simulation results that the proposed broadband filters give consistent performance regardless of the gap location in the unit cell, which will further extend their use in practical applications.

Computationally Assisted (Solid-State Density Functional Theory) Structural (X-ray) and Vibrational Spectroscopy (FT-IR, FT-RS, TDs-THz) Characterization of the Cardiovascular Drug Lacidipine

Kacper Drużbicki, Jadwiga Mielcarek, Anna Kiwilsza, Loic Toupet, Eric Collet, Aleksandra Pajzderska, and Jan Wąsicki


The structural properties of a second-generation dihydropyridine calcium antagonist, lacidipine, were explored by combining low-temperature X-ray diffraction with optical vibrational spectroscopy and periodic density functional theory (PBC DFT) calculations. Crystallographic analysis cannot discriminate between two possible molecular symmetries in crystals made of pure lacipidine: the space group Ama2, where the lacipidine molecule lies on mirror symmetry, or a Cc space group with distorted lacipidine molecules. Intermolecular interactions analysis reveals an infinite net of moderate-strength N–H···O hydrogen-bonds, which link the molecular units toward the crystallographic b-axis. Weak interactions were identified, revealing their role in stabilization of the crystal structure. The vibrational dynamics of lacidipine was thoroughly explored by combining infrared and Raman spectroscopy in the middle- and low-wavenumber range. The given interpretation was fully supported by state-of-the-art solid-state density functional theory calculations (plane-wave DFT), giving deep insight into the vibrational response and providing a complex assignment of spectral features. The vibrational analysis was extended onto the lattice-phonon range by employing time-domain terahertz spectroscopy. Analysis of the anisotropic displacement parameters suggests noticeable dynamics of the terminal (tert-butoxycarbonyl)vinyl moiety. The terahertz study provides direct experimental evidence of “crankshaft” type motions in the terminal chain. By combining low-wavenumber vibrational spectroscopy with the first-principles calculations, we were able to prove that the quoted thermodynamically stable phase corresponds to the monoclinic Cc space group.

Experimental (X-Ray, IR, RS, INS, THz) and Solid-State DFT Study on (1:1) Co-crystal of Bromanilic Acid and 2,6-Dimethylpyrazine

Katarzyna Łuczyńska , Kacper Drużbicki , Krzysztof Lyczko , and Jan Czeslaw Dobrowolski


A combined structural, vibrational spectroscopy and solid-state DFT study of hydrogen-bonded complex of bromanilic acid with 2,6-dimethylpyrazine is reported. The crystallographic structure was determined by means of low-temperature single-crystal X-ray diffraction, which reveals the molecular units in their native protonation states, forming one-dimensional infinite nets of moderate-strength O∙∙∙H-N hydrogen bonds. The nature of the crystallographic forces, stabilizing the studied structure, has been drawn by employing the non-covalent interactions analysis. It was found that in addition to the hydrogen bonding, the intermolecular forces are dominated by stacking interactions and C-H∙∙∙O contacts. The thermal and calorimetric analysis was employed to probe stability of the crystal phase. The structural analysis was further supported by computationally assisted 13C CP/MAS NMR study, providing a complete assignment of the recorded resonances. The vibrational dynamics was explored by combining the optical (IR, Raman, TDs-THz) and inelastic neutron scattering (INS) spectroscopy techniques with the state-of-the-art solid-state density functional theory (DFT) computations. Despite of quasi-harmonic approximation assumed throughout the study, an excellent agreement between the theoretical and experimental data was achieved over the entire spectral range, allowing for deep and possibly thorough understanding of the vibrational characteristics of the system. Particularly, the significant influence of the long-range dipole coupling on the IR spectrum has been revealed. Based on a wealth of information gathered, the recent implementation of dispersion-corrected linear-response scheme has been extensively examined.

Passive imaging of concealed objects in terahertz and long-wavelength infrared

Marcin Kowalski, Mariusz Kastek, Michal Walczakowski, Norbert Palka, and Mieczyslaw Szustakowski


Terahertz and infrared radiation have unique properties applicable to the field of surveillance and security systems. We investigated the possibility of detecting potentially dangerous objects covered by various types of clothing using passive imagers operating at 1.2 mm (250 GHz) and long-wavelength infrared at 6–15 μm (20–50 THz). We developed a measurement methodology that assumes to investigate theoretical limitations, performance of imagers, and physical properties of fabrics. To evaluate stability of the detection capabilities of imagers, we performed measurement sessions each lasting 30 min. We present a theoretical comparison of the two spectra and results of experiments using state-of-the-art equipment.
