  "abstract": "We study the spin Hall effect in the kagom\\'{e} lattice with Rashba spin-orbit coupling. The conserved spin Hall conductance $\\sigma_{xy}^{s}$ (see text) and its two components, i.e., the conventional term $\\sigma_{xy}^{s0}$ and the spin-torque-dipole term $\\sigma_{xy}^{s\\tau}$, are numerically calculated, which show a series of plateaus as a function of the electron Fermi energy $\\epsilon_{F}$. A consistent two-band analysis, as well as a Berry-phase interpretation, is also given. We show that these plateaus are a consequence of the various Fermi-surface topologies when tuning $\\epsilon_{F}$. In particular, we predict that compared to the case with the Fermi surface encircling the $\\mathbf{\\Gamma}$ point in the Brillouin zone, the amplitude of the spin Hall conductance with the Fermi surface encircling the $\\mathbf{K}$ points is twice enhanced, which makes it highly meaningful in the future to systematically carry out studies of the $\\mathbf{K}$-valley spintronics.",
