This work is focused on the study of charged wormholes in the following two aspects: (i) to obtain exotic matter free effective charged wormhole solutions and (ii) to determine deflection angle for gravitational lensing effect. We have defined a novel redshift function, obtained wormhole solutions using the background of f(R) theory of gravity and found the regions obeying the weak energy condition. Further, the gravitational lensing effect is analyzed by determining the deflection angle in terms of strong field limit coefficients.

f(R) 重力下的带电可穿越虫洞

这项工作主要从以下两个方面研究带电虫洞：（i）获得无外来物质的有效带电虫洞解决方案和（ii）确定引力透镜效应的偏转角。我们定义了一个新的红移函数，使用背景得到虫洞解F(R)引力理论，发现服从弱能量条件的区域。此外，通过根据强场限制系数确定偏转角来分析引力透镜效应。
