Trong nghiên cứu này, việc sử dụng đầu sợi quang có hình nón được phủ Graphene Oxide đã giảm (rGO) làm cảm biến được điều tra. Các nano-composite rGO được phủ trên cảm biến sợi nón đã được đặc trưng hóa bằng phương pháp nhiễu xạ tia X (XRD), phổ Raman, và kính hiển vi điện tử quét phát xạ trường (FESEM). Việc tối ưu hóa lớp rGO và các thông số đầu sợi nón đã được thực hiện và khả năng cảm biến của...... hiện toàn bộ

Phase functions as solutions of integral equationsJournal of the European Optical Society-Rapid Publications - Tập 13 - Trang 1-7 - 2017
Margarita L. Shendeleva
A phase function is an important characteristic of a scattering medium. A method to derive new analytic phase functions is proposed. The relation between a phase function and an angle-averaged single-scattering intensity, derived earlier [M. L. Shendeleva, J. Opt. Soc. Am. A 30, 2169 (2013)], is considered as an integral equation for a phase function. This equation is classified as an Abel integra...... hiện toàn bộ
Raman spectroscopic detection of interleukin-10 and angiotensin converting enzymeJournal of the European Optical Society-Rapid Publications - Tập 17 - Trang 1-5 - 2021

In this report we present a confocal Raman system to identify the unique spectral features of two proteins, Interleukin-10 and Angiotensin Converting Enzyme. Characteristic Raman spectra were successfully acquired and identified for the first time to our knowledge, showing the potential of Raman spectroscopy as a non-invasive investigation tool for biomedical applications.
Focusing of THz waves with a microsize parabolic reflector made of graphene in the free spaceJournal of the European Optical Society-Rapid Publications - Tập 13 - Trang 1-8 - 2017
Taner Oguzer, Ayhan Altintas, Alexander I. Nosich
The scattering of H- and E-polarized plane waves by a two-dimensional (2-D) parabolic reflector made of graphene and placed in the free space is studied numerically. To obtain accurate results we use the Method of Analytical Regularization. The total scattering cross-section and the absorption cross-section are computed, together with the field magnitude in the geometrical focus of reflector. The ...... hiện toàn bộ
Scattering from metamaterial coated nihility sphereJournal of the European Optical Society-Rapid Publications - Tập 13 - Trang 1-8 - 2017
A. Ghaffar, M. M. Hussan, Majeed A. S. Alkanhal, Sajjad ur Rehman
To show the Back-Scattering efficiencies of nihility sphere become non-zero, scattering from metamaterial coated nihility sphere has been carried out in the presented work. The field phasors are expanded in terms of spherical wave vector function along with assumed scattering coefficients. Boundaries conditions are applied at each interface, i.e., free space- metamaterial coating and metamaterial ...... hiện toàn bộ
Complementary analysis of Mueller-matrix images of optically anisotropic highly scattering biological tissuesJournal of the European Optical Society-Rapid Publications - Tập 14 - Trang 1-8 - 2018

Using optical techniques for tissue diagnostics (so-called ‘optical biopsy’) has been a subject of extensive research for many years. Various groups have been exploring different spectral and/or imaging modalities (e.g. diffuse reflectance spectroscopy, autofluorescence, Raman spectroscopy, optical coherence tomography (OCT), polarized light microscopy, etc.) for biomedical applications. In this p...... hiện toàn bộ
