Using a one-way coupled model of neutral gas flow and plasma dynamics we report a mechanism to explain the ring-shaped emission pattern that has been observed experimentally in plasma bullets at atmospheric pressure. We solve a fluid model with the local field approximation in one-dimensional cylindrical coordinates, corresponding to a cross-section of a plasma bullet. Pulselike uniform electric field is assumed to be applied perpendicular to the simulation domain. Time and spatially resolved spectroscopic measurements support the simulation results.

    Single-surface multipactor is studied within a plane-parallel model for the case when the rf electric field is normal to the surface of emission and the electron return to this surface is caused by the action of a dc electric field. The corresponding resonance zones are found for finite initial...
