Coherent control of high efficiency metasurface beam deflectors with a back partial reflector

APL Photonics, 2017
Recently, coherent control of absorption in metallic metasurfaces has been demonstrated, and this phenomenon was applied to intriguing light-by-light switching operation. Here we experimentally demonstrate coherent control

The Gravitational Deflection of Light in f(R)-Gravity [PDF]

International Journal of Theoretical Physics, 2014
The fact that the gravitation could deflect the light trajectory has been confirmed by a large number of observation data, that is consistent with the result calculated by Einstein's gravity. F(R)-gravity is the modification of Einstein's gravity. According to the field equations obtained by the action of the f(R) form, we get a similar Schwarzschild ...

GPU Ray Tracing for the Analysis of Light Deflection in Inhomogeneous Refractive Index Fields of Hot Tailored Forming Components

Sensors
In hot-forming, integrating in situ quality monitoring is essential for the early detection of thermally induced geometric deviations, especially in the production of hybrid bulk metal parts. Although hybrid components are key to meeting modern technical

Shadow of the Moon and general relativity: Einstein, Dyson, Eddington and the 1919 light deflection [PDF]

Revista Brasileira de Ensino de Física, 2019
The eclipse of the Sun of 1919 was fundamental in the development of physics and earns a high place in the history of science. Several players took part in this adventure.

Deflection of Light during a Solar Eclipse [PDF]

Nature, 1920
PROF. ANDERSON has suggested in NATURE that the apparent displacement of stars observed during the solar eclmay be ascribed to an unusual form of refraction in the terrestrial atmosphere. The discussion which has followed shows some lack of agreement as to the importance of such a refraction effect. I wish to suggest that it might, perhaps, be possible

Deflection of light in equatorial plane due to Kerr-Taub-NUT body [PDF]

Serbian Astronomical Journal, 2017
According to General Relativity, there are factors like mass, rotation, charge and presence of Cosmological constant that can influence the path of light ray.

Spherical Skyrmion black holes as gravitational lenses

European Physical Journal C: Particles and Fields, 2018
In this article, we extend the strong deflection limit to calculate the deflection angle for a class of geometries which are asymptotically locally flat.

Light propagation and gravitational lensing effects in charged Kalb–Ramond spacetime in nonlinear electrodynamics

Physics Letters B
In this work, we theoretically investigate the deflection of light for strong- and weak-field regimes in the background of an electrically charged BH described in Kalb-Ramond gravity, which introduces the Lorentz symmetry violation parameter l, as well ...
