In this work, we extend the work of gravastars to analyze the role of electromagnetic field in $f(R,T)$ gravity. We consider the irrotational cylindrically symmetric geometry and established the $f(R,T)$ field equations and conservation laws. After considering charged exterior geometry, the mathematical quantities for evaluating Israel junction conditions are being calculated. The mass of the gravastar-like cylindrical structure is calculated through the equations of motion at the hypersurface in the presence of an electromagnetic field. The behavior of electric charge on the length of the thin shell, energy content, and entropy of gravastar is being studied graphically. We concluded that charge has an important role in the length of the thin shell, energy content, and entropy of gravastar.

在这项工作中，我们扩展了引力星的工作，以分析电磁场在 $F（\mathrm{[R}，Ť）$重力。我们考虑了非旋转圆柱对称几何并建立了$F（\mathrm{[R}，Ť）$场方程和守恒定律。在考虑带电的外部几何形状之后，正在计算用于评估以色列交界处状况的数学量。在存在电磁场的情况下，通过超表面处的运动方程式可以计算出格拉瓦斯塔状圆柱结构的质量。用图形研究了电荷在薄壳长度，能量含量和重力熵上的行为。我们得出的结论是，电荷在薄壳的长度，能量含量和引力子的熵中起着重要作用。
