We consider the superfluid density tensor /rho//sub /ital s// in both singlet and triplet unconventional superconductors. We develop theoretical expressions for /rho//sub /ital s// which incorporate both band-structure effects and impurity scattering; these expressions simplify considerably in the Ginzburg-Landau region close to /ital T//sub /ital c//. We also present the results of numerical calculations showing /rho//sub /ital s// as a function of temperature for several different unconventional order parameters.
