Gravitational lensing in 4-D Einstein–Gauss–Bonnet gravity in the presence of plasma

In this paper we have assumed a weak-field regime to explore the gravitational lensed photons in 4 dimensional Einstein–Gauss–Bonnet gravity, which is very much limelight these days. The investigation conducted three distinct paradigms: uniform plasma, singular isothermal sphere and non-singular sphere. lensing angle associated with distribution factor of medium individually derived for each case further utilized study magnification image source brightness, selectively plasma attained results are brought forth contrast standard Schwarzschild geometry.
