摘要：

The modified theories of gravity, especially the f(Q) theory, have attracted much attention in recent years. This study delves into non-static plane-symmetric solutions within the framework of this theory, employing a metric approach. The field equations are addressed with the incorporation of the Hubble parametrization H=H0 2 [1+(1+z)(2(1+beta)]1/2). The determination of optimal values for free parameters is achieved through the analysis of 57 data points of the Hubble parameter H(z). Additionally, the study explores the behavior of various cosmological parameters, including the deceleration parameter (q), energy density (rho), pressure (p), and equation of state (EoS) parameter (omega), comparing them with observational findings. To validate the results, energy conditions and state finder analysis are undertaken. Ultimately, it is established that our model exhibits behavior akin to the Lambda CDM model. Finally, we found that our model behaves similar to the Lambda CDM model.
