We report on a computational study of the intersection of plasma filaments in a dielectric barrier discharge with small particulates suspended in air or residing on surfaces. The relative location of the particle with respect to the streamer axis is important on plasma time scale considered in the paper. The particulates residing on the substrate surface are partially enveloped by the sheath formed beneath the filament and the substrate. Ion energies and fluxes incident on the particulate depend on dielectric properties of the underlying substrate materials.
