Magneto-transports in a ballistic transport regime were studied in a double-sided corrugation-gated wire. A central peak at zero field was observed along with several symmetric peaks in the low temperature magneto-resistance. Although the side peaks were considered to have come from a multiple back scattering of electrons, the central peak depends strongly on the temperature, and could be explained by a ballistic weak localization effect. It can also be discussed by a numerical simulation of the wave function scarring in the corrugation units. It was observed that the relationship between the ballistic weak localization and the wave function scarring imparted important information on the dynamic behavior of electron transport in the corrugation wire.
