THE CASIMIR FORCE BETWEEN METALLIC MIRRORS [PDF]
The Ninth Marcel Grossmann Meeting, 2002 In order to compare recent experimental results with theoretical predictions we study the influence of finite conductivity of metals on the Casimir effect. The correction to the Casimir force and energy due to imperfect reflection and finite temperature are evaluated for plane metallic plates where the dielectric functions of the metals are modeled by ...

Teoriya i praktika arkheologicheskikh issledovaniy, 2016 The article presents the circumstances of discovery in the territory of the Baraba forest-steppe (near Lake Wait, Karagatskom in the Novosibirsk region) of a metal mirror, heavily coated with oxides. The find has been subjected to the restoration at the Institute of Archaeology and Ethnography of the Siberian Branch of the Russian Academy of Sciences ...

Measurement and correction of two-sided freeform optical elements with combined tactile-optical metrology equipment [PDF]
EPJ Web of Conferences, 2019 Freeform optical elements are state of the art for several years to fabricate very high performance optical systems with the necessity of, e.g., strong folding in mirror system or correction of typical asymmetric aberrations in mirror systems as well as ...

FDTD Simulation and Quantitative Analysis of Dipole Mirror Effect
Taiyuan Ligong Daxue xuebao, 2022 The local plasma resonance of noble metal nanoparticles can significantly enhance the visible light response of wide bandgap semiconductors, but the absorption coefficient of noble metal nanoparticles with small volume and strong scattering is low, which

MMI resonators based on metal mirrors and MMI mirrors: an experimental comparison
Optics Express, 2015 We report, to the best of our knowledge, the first experimental proof of MMI-based resonators. The resonators have been designed and fabricated on a micron-scale silicon photonics platform and are based on different reflectors suitably placed on two of the four ports of 2x2 MMIs with uneven splitting ratios, namely 85:15 and 72:28.

Electrodeposition of mirror surface β-W films in molten CsF–CsCl–WO3
Electrochemistry Communications, 2021 In this study we report, for the first time, a thick β-W film with a mirror-like surface prepared through electrodeposition involving a CsF–CsCl eutectic melt combined with 2.0 mol% of WO3 at 773 K.

Suppression method for rebound amount of the internal mirror model of an SLR camera
Mechanical Engineering Journal, 2015 In this study, the rebound vibration characteristics of the internal mirror of an SLR camera are investigated using experimental models. The mechanism of the mirror rebound phenomena is tested by using four types of rectangular metal plate models.

Optical magnetic mirrors without metals
Optica, 2014 The reflection of an optical wave from a metal, arising from strong interactions between the optical electric field and the free carriers of the metal, is accompanied by a phase reversal of the reflected electric field. A far less common route to achieve high reflectivity exploits strong interactions between the material and the optical magnetic field ...
