摘要：

Within a separable pairing model of the form [cos (k(X)a)-cos(k(Y)a)] in the copper oxide plane, with k(X), k(Y) momentum and ''a'' the lattice parameter, we calculate the temperature dependence of the penetration depth by performing a full integration over the Brillouin Zone at fixed value of chemical potential. Strong coupling effects are investigated in a simple model as is the effect of impurity scattering both in Born approximation (weak scattering) and in the unitary limit (strong scattering).
