Here, $R$ represents the Ricci scalar and $T_{ab}$ is the energy-momentum tensor. Specifically considering the linear form $f\\left(R,T_{ab}T^{ab}\\right)=R+\\gamma T_{ab}T^{ab}$, we demonstrate the existence of numerous wormhole solutions, wherein the matter fields satisfy all energy conditions, these being the null, weak, strong, and dominant energy conditions.
