We study transport in a smooth random magnetic field, with emphasis oncomposite fermions (CF) near half-filling of the Landau level. When either theamplitude of the magnetic field fluctuations or its mean value $\bar B$ islarge enough, the transport is of percolating nature. While at $\bar{B}=0$ thepercolation effects enhance the conductivity $\sigma_{xx}$, increasing $\bar B$(which corresponds to moving away from half-filling for the CF problem) leadsto a sharp falloff of $\sigma_{xx}$ and, consequently, to the quantumlocalization of CFs. We demonstrate that the localization is a crucial factorin the interplay between the Shubnikov-de Haas and quantum Hall oscillations,and point out that the latter are dominant in the CF metal.Comment: 4 pages, RevTe
