  By event-driven molecular dynamics simulations we investigate
magneto-transport in a two-dimensional model with randomly distributed
scatterers close to the field-induced localization transition. This transition
is generated by percolating skipping orbits along the edges of obstacle
clusters. The dynamic exponents differ significantly from those of the
conventional transport problem on percolating systems, thus establishing a new
dynamic universality class. This difference is tentatively attributed to a
weak-link scenario, which emerges naturally due to barely overlapping edge
trajectories. We make predictions for the frequency-dependent conductivity and
discuss implications for active colloidal circle swimmers in a heterogeneous
environment.
