Horocycles of Light in a Ferrocell

open access: yesCondensed Matter, 2021
We studied the effects of image formation in a device known as Ferrocell, which consists of a thin film of a ferrofluid solution between two glass plates subjected to an external magnetic field in the presence of a light source.

Optical processes in photosynthesis [PDF]

open access: yesСибирский лесной журнал, 2018
A review of the state and analysis of works related to optical processes of photosynthesis are given. Particular attention is paid to the work on the investigation of these processes in iridoplasts and chloroplasts with photonic crystal structure. From a

Darkfield colors from multi-periodic arrays of gap plasmon resonators

open access: yesNanophotonics, 2020
We present results on colors of metal disk arrays viewed under a darkfield microscope and show that the darkfield colors can be manipulated independently of the brightfield colors.

Algorithmically Optimized Hemispherical Dome as a Secondary Optical Element for the Fresnel Lens Solar Concentrator

open access: yesApplied Sciences, 2019
The significance of this work lies in the development of a novel code-based, detailed, and deterministic geometrical approach that couples the optimization of the Fresnel lens primary optical element (POE) and the dome-shaped secondary optical element ...

Optical transmission theory for metal-insulator-metal periodic nanostructures

open access: yesNanophotonics, 2016
A semi-analytical formalism for the optical properties of a metal-insulator-metal periodic nanostructure using coupled-mode theory is presented. This structure consists in a dielectric layer in between two metallic layers with periodic one-dimensional ...
