Gravitational Lensing Using Werner's Method in Cartesian-like Coordinates
Zonghai Li
The Gibbons-Werner method for calculating deflection angles using the Gauss-Bonnet theorem and optical/Jacobi metric has become widely popular in recent years. Werner extended this…

A Novel Method for Calculating Deflection Angle with Finite-Distance Correction
Zonghai Li
In recent study in Ref.[7] (arXiv: 2401.12525), we have introduced a method aimed at calculating the weak-field asymptotic deflection angle. This method offers an efficient computa…

A Novel Method for Calculating Deflection Angle
Zonghai Li
In this paper, we introduce a method for calculating the deflection angle in the weak-field approximation, applicable to both null and timelike rays. By combining the trajectory eq…
