Flexibly tunable surface plasmon resonance by strong mode coupling using a random metal nanohemisphere on mirror

open access: yesNanophotonics, 2020
We propose a unique random metal nanohemisphere on mirror (NHoM) structure to tune the surface plasmon (SP) resonance in a flexible manner. The SP resonance peak was split into two peaks owing to the strong coupling between the SP mode in the metal ...

Synthesis and properties of mirror-like large-grain graphite films [PDF]

open access: yesNature Communications
Graphite films with large grain sizes have been reportedly obtained by using metal as catalysts, but the obtained graphite is mostly heavily wrinkled, thus containing defects that degrade its properties.

Employment of gradient metal-film output mirrors in terahertz discharge lasers [PDF]

open access: yesРадиофизика и электроника, 2021
Subject and Purpose. The problem of output beam matching with the waveguide transmission line often arises when using terahertz lasers. The special quasi-optical devices that are used to combat the problem lead to radiation losses and additional material

Metal Wear of the Ancient Nomads of the Altai Foothills: Х-ray fluorescence analysis and cultural-chronological attribution

open access: yesПоволжская археология, 2022
For a long time, the Mayemir (Mayemer) culture of the Early Saka period was considered insufficiently well-studied. By now the range of sources has expanded considerably with the excavation of barrows at several burial grounds.
