Gravitational Lensing in Weyl Gravity
, 2019 We calculate the deflection angle of light from a distant source by a galaxy cluster in Weyl's conformal gravity. The general method of calculation is first applied to calculate the deflection angle in Schwarzschild-de Sitter (Kottler) spacetime.

Strong deflection lensing by charged black holes in scalar-tensor gravity [PDF]
, 2014 We examine a class of charged black holes in scalar-tensor gravity as gravitational lenses. We find the deflection angle in the strong deflection limit, from which we obtain the positions and the magnifications of the relativistic images.

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.

Physics Letters B, 2022 The objective of this paper is to analyze the weak deflection angle of Einstein-Gauss-Bonnet gravity in the presence of plasma medium. To attain our results, we implement the Gibbons and Werner approach and use the Gauss-Bonnet theorem to Einstein ...

Gravitational Lensing Corrections in Flat LambdaCDM Cosmology
, 2010 We compute the deflection angle to order (m/r_0)^2 and m/r_0*Lambda r_0^2 for a light ray traveling in a flat LambdaCDM cosmology which encounters a completely condensed mass region.

Frontiers in Earth Science, 2023 In practice, constant-resistance, energy-absorbing, and anti-scouring bolts inevitably deflect at an angle from the coal wall and other bearing surfaces, eventually giving way and losing their energy-absorbing function.

Light bending in $F\left[g(\square)R\right]$ extended gravity theories
, 2018 We show that in the weak field limit the light deflection alone cannot distinguish between different $R + F[g(\square)R]$ models of gravity, where $F$ and $g$ are arbitrary functions.

Self-deflecting plasmonic lattice solitons and sur-face modes in chirped plasmonic arrays [PDF]
, 2015 We show that chirped metal-dielectric waveguide arrays with focusing cubic nonlinearity can support plasmonic lattice solitons that undergo self-deflection in the transverse plane. Such lattice solitons are deeply-subwavelength self-sustained excitations,

Analytical Investigation of Aircraft Nosewheel Deflection Limit According to the Taxiing Speed
Hangkong gongcheng jinzhan, 2021 The rollover can be encountered due to excessive deflection of the nosewheel during takeoff and landing stages of the aircraft, so the nose-wheel deflection should be reasonably limited according to the taxiing speed.Based on the principle of the ...
