Zusammenfassung:Gravitational weak lensing around a Schwarzschild-like black hole (BH) has been deeply studied in the presence of a plasma medium. The obtained results have shown that the effect of parameter a on the deflection angle of light rays around BH in Schwarzschild-like spacetime is perceptible. With an increase of parameter a , deflection angle of photon decreases, and the effect of plasma on deflection angle is opposite. The total magnification of the image source due to gravitational lensing has been also studied taking into account the effect of coupling parameter a in the presence of plasma around the black hole.
