Abstract. In this study, exploration of a five-dimensional, plane-symmetric model incorporating a wet dark fluid (WDF) is presented, posited as a viable candidate for explaining dark energy (DE) within the f(R) gravity theory, where R denotes the Ricci scalar. For the DE component, the equation of state is modelled as p = ω(ρ - ρ^*). In this research, a definite solution of the field equation is obtained using power law assumption and special form of deceleration parameter. Certain geometrical and physical aspects of the model were examined, and the function f(R) along with the Ricci scalar R was derived.
