We present numerical simulations of shot noise suppression in low-dimensional systems, focusing on the different limiting values of the Fano factor (ratio of the current noise power spectral density to the full shot noise power spectral density) for specific structures such as diffusive conductors, regular antidot lattices, chaotic cavities. We also study the dependence of the Fano factor for a chaotic cavity on magnetic field, proposing an intuitive explanation for the results, based on the ratio of the classical cyclotron radius to the width of the apertures defining the cavity.
