Abstract
We have observed several symmetrical paired peaks against the zero field in the magnetoresistance of the double corrugation gated wires. These symmetr ical peaks can be explained by each commensurate trajectory due to an inter nal magnetic focusing in the ballistic cavity formed in the quantum dot of the corrugation unit.
