Gravitational Lensing Analyzed by Graded Refractive Index of Vacuum
Xing-Hao Ye, Qiang Lin
We found strong similarities between the gravitational lensing and the conventional optical lensing. The similarities imply a graded refractive index description of the light defle…

A Simple Optical Analysis of Gravitational Lensing
Xing-Hao Ye, Qiang Lin
We analyzed the influence of static gravitational field on the vacuum and proposed the concept of inhomogeneous vacuum. According to the corresponding Fermat's principle in the gen…

The Deviation of the Vacuum Refractive Index Induced by a Static Gravitational Field
Xing-Hao Ye, Qiang Lin
We analyzed the influence of static gravitational field on the vacuum and proposed the concept of inhomogeneous vacuum. According to the observational result of the light deflectio…
