Abstract
We study coherent magnetotransport in finite antidot arrays in four-te rminal geometry. The calculated longitudinal resistance is in very goo d agreement with experimental data. The quantum-mechanical current den sity is visualized, and we discuss its relation to classical electron dynamics. A pronounced commensurate peak in the longitudinal resistanc e is attributed to the enhancement of the transmission in the transver se direction due to runaway trajectories.
