Terahertz BWO-Spectrosopy
Boris Gorshunov,Alexander G. Volkov,Igor E. Spektor,A. S. Prokhorov,A. A. Mukhin,Martin Dressel,S. Uchida,Alois Loidl +7 more
TL;DR: In this article, the backward-wave oscillators (BWOs) were used for terahertz-sub-Terahertz (THz-subTHz) spectrometers, based on continuously frequency-tunable coherent sources of radiation.
Journal ArticleDOI
BWO Generators for Terahertz Dielectric Measurements
Gennady A. Komandin,S. V. Chuchupal,Sergey P. Lebedev,Yurii G. Goncharov,A. F. Korolev,O. E. Porodinkov,Igor E. Spektor,A. A. Volkov +7 more
TL;DR: In this paper, a universal magnetic focusing system on a permanent magnet with a protective housing shielding the magnetic field was developed for stable generation of radiation with a frequency of up to 2.1 THz without geometry change.
Journal ArticleDOI
Wide-aperture aspherical lens for high-resolution terahertz imaging
Nikita V. Chernomyrdin,Maxim E. Frolov,Sergey P. Lebedev,Igor V. Reshetov,Igor E. Spektor,Viktor L. Tolstoguzov,Valeriy E. Karasik,Alexei M. Khorokhorov,Kirill I. Koshelev,A. O. Schadko,Stanislav O. Yurchenko,Kirill I. Zaytsev +11 more
TL;DR: To highlight high resolution in the THz images, the wide-aperture lens has been employed for studying printed electronic circuit board containing sub-wavelength-scale elements and the observed results justify the high efficiency of the proposed lens design.
Journal ArticleDOI
Solid immersion terahertz imaging with sub-wavelength resolution
Nikita V. Chernomyrdin,A. O. Schadko,Sergey P. Lebedev,Viktor L. Tolstoguzov,Vladimir N. Kurlov,Igor V. Reshetov,Igor E. Spektor,Maksim Skorobogatiy,Stanislav O. Yurchenko,Kirill I. Zaytsev +9 more
TL;DR: In this article, the authors developed a method of solid immersion THz imaging, a noncontact technique employing the THz beam focused into evanescent-field volume and allowing strong reduction in the dimensions of THz caustic.
Journal ArticleDOI
Metallic and dielectric metasurfaces in photoconductive terahertz devices: A review
A. E. Yachmenev,D. V. Lavrukhin,I. A. Glinskiy,Nikolay V. Zenchenko,Yurii G. Goncharov,Igor E. Spektor,Rustam A. Khabibullin,Rustam A. Khabibullin,Taiichi Otsuji,Dmitry Ponomarev +9 more
TL;DR: In this paper, the authors highlight recent and novel trends focused on metallic (plasmonic) and dielectric metasurfaces in photoconductive terahertz (THz) devices.
