## Charged particle reflection from an artificially structured boundary that produces a spatially periodic magnetostatic field

Charged particle reflection away from an artificially structured boundary is studied by computer simulation. The artificially structured boundary produces a spatially periodic static magnetic field such that the spatial period of the field is much smaller than the dimensions of a source of incident charged particles. A planar artificially structured boundary comprised of a sequence of parallel wires is considered. The wires carry currents in alternating directions and produce the magnetic field. A classical trajectory Monte Carlo study is reported. The motion of charged particles that approach the artificially structured boundary at small or grazing angles of incidence transverse tomore »
