Dielectric microparticles for enhanced optical imaging: a FDTD analysis of contrast and resolution

Autor: Bekirov, Arlen, Wang, Zengbo, Lukyanchuk, Boris

This paper presents a comprehensive numerical analysis of super-resolution imaging using dielectric microparticles, employing the Finite-Difference Time-Domain (FDTD) method to elucidate the mechanisms that enable resolution enhancements beyond the d

Optical super-resonances in dielectric microsphere particles

Autor: Wang, Zengbo, Lukyanchuk, Boris, Wu, Baidong, Yan, Bing, Assel, Ahmetova, Yaminsky, Igor, Yu, Haibo, Liu, Lianqing

Extreme field localization and giant field enhancement are often achieved by using plasmonic nanostructures and metamaterials such as strongly coupled silver nanoparticles.Dielectric particles and structures can focus light beyond the diffraction lim

Subwavelength Imaging with Dielectric Metamaterial Solid-Immersion Lens

Autor: Fan, Wen, Yan, Bing, Wang, Zengbo, Lukyanchuk, Boris, Wu, Limin

Publikováno v: Fan, W., Yan, B., Wang, Z., & Wu, L. (2016). Three-dimensional all-dielectric metamaterial solid immersion lens for subwavelength imaging at visible frequencies. Science advances, 2(8), e1600901

The limited resolution of a conventional optical microscope stems from the fact that the subwavelength information of an object is carried by evanescent waves, which exponentially decays in space and cannot reach the imaging plane. We introduce here

Seeing the unseen: observation of an anapole with dielectric nanoparticles

Autor: Miroshnichenko, Andrey E., Evlyukhin, Andrey B., Yu, Ye Feng, Bakker, Reuben M., Chipouline, Arkadiy, Kuznetsov, Arseniy I., Lukyanchuk, Boris, Chichkov, Boris N., Kivshar, Yuri S.

Nonradiating current configurations attract attention of physicists for many years as possible models of stable atoms in the field theories. One intriguing example of such a nonradiating source is known as anapole (which means without poles in Greek)

Optical generation of intense ultrashort magnetic pulses at the nanoscale

Autor: Tsiatmas, Anagnostis, Atmatzakis, Evangelos, Papasimakis, Nikitas, Fedotov, Vassili, Lukyanchuk, Boris, Zheludev, Nikolay I., de Abajo, F. Javier Garcia

Publikováno v: New Journal of Physics 15, 113035 (2013)

Generating, controlling, and sensing strong magnetic fields at ever shorter time and length scales is important for both fundamental solid-state physics and technological applications such as magnetic data recording. Here, we propose a scheme for pro
