Numerical analysis and experimental study of terahertz solid immersion microscopy
Nikita V. Chernomyrdin,Nikita V. Chernomyrdin,Nikita V. Chernomyrdin,Vladislav A. Zhelnov,Vladislav A. Zhelnov,A. S. Kucheryavenko,A. S. Kucheryavenko,Irina N. Dolganova,Irina N. Dolganova,Irina N. Dolganova,Gleb M. Katyba,Valery E. Karasik,Igor V. Reshetov,Kirill I. Zaytsev,Kirill I. Zaytsev +14 more
TL;DR: Terahertz solid immersion microscopy is a modality of THz imaging, which allows one to overcome the Abbe diffraction limit and provides high energy efficiency due to the absence of subwavelength apertures and probes in an optical scheme.
Journal ArticleDOI
Terahertz Microscope Based on Solid Immersion Effect for Imaging of Biological Tissues
Nikita V. Chernomyrdin,Nikita V. Chernomyrdin,A. S. Kucheryavenko,A. S. Kucheryavenko,Elena N. Rimskaya,Irina N. Dolganova,Irina N. Dolganova,Vladislav A. Zhelnov,P. A. Karalkin,A. A. Gryadunova,Igor V. Reshetov,D. V. Lavrukhin,Dmitry Ponomarev,Valery E. Karasik,Kirill I. Zaytsev,Kirill I. Zaytsev +15 more
TL;DR: In this article, the authors proposed a method of terahertz microscopy for imaging of biological tissues with a subwavelength spatial resolution, which makes it possible to surmount the Abbe diffraction limit and ensure a sub-wavelength resolution due to the solid immersion effect.
Journal ArticleDOI
Object-dependent spatial resolution of the reflection-mode terahertz solid immersion microscopy.
Vladislav A. Zhelnov,Kirill I. Zaytsev,A. S. Kucheryavenko,Gleb M. Katyba,Irina N. Dolganova,Dmitry Ponomarev,Vladimir N. Kurlov,Maksim Skorobogatiy,Nikita V. Chernomyrdin +8 more
TL;DR: In this article, a numerical analysis, using the finite-difference time-domain technique, and an experimental study, using a set of objects with distinct refractive indexes, were performed in order to uncover, for the first time, the object-dependent spatial resolution of the THz solid immersion microscopy.
Journal ArticleDOI
Opal-based terahertz optical elements fabricated by self-assembly of porous SiO 2 nanoparticles
V. E. Ulitko,Gleb M. Katyba,Vladislav A. Zhelnov,I. M. Shmyt’ko,G. A. Emel’chenko,I. E. Spector,Vladimir M. Masalov,Vladimir N. Kurlov,Kirill I. Zaytsev,Maksim Skorobogatiy +9 more
TL;DR: In this paper, the authors study artificial opals as a promising material platform for terahertz (THz) optics and propose two distinct approaches for the fabrication of bulk THz optics from these novel materials.
Journal ArticleDOI
Tunable THz flat zone plate based on stretchable single-walled carbon nanotube thin film
Gleb M. Katyba,Nikita I. Raginov,Eldar M. Khabushev,Vladislav A. Zhelnov,Andrei Gorodetsky,Davit Ghazaryan,Mikhail S. Mironov,Dmitry V. Krasnikov,Yu. G. Gladush,James Lloyd-Hughes,Albert G. Nasibulin,Aleksey V. Arsenin,Valentyn S. Volkov,Kirill I. Zaytsev,Maria G. Burdanova +14 more
TL;DR: In this article , the authors presented an approach for the creation of mechanically tunable zone plate lenses in the THz range, which consisted of single-walled carbon nanotube (SWCNT) thin films of predetermined design integrated with stretchable polymer films.
