We compute the pion and kaon matrix elements that yield the transverse-momentum-dependent parton distribution functions. We use an $N_f=2+1+1$ twisted mass fermion ensemble of lattice size $24^3 x 48$, lattice spacing $a=0.093$ fm, and a pion mass of $350$ MeV. We employ momentum smearing to improve the signal of the boosted pion and kaon states. We also study the mixing pattern of the extended operators with an asymmetric Wilson staple under renormalization and implement an RI/MOM scheme for the non-perturbative renormalization.
