摘要：
The transmission properties of a circular, right-angle bend in a two-dimensional electron waveguide are calculated. Significant reflections from such a bend would have serious consequences for the development of a quantum electron waveguide technology. The results show nearly perfect transmission around the bend, except for energies very close to the threshold for propagation in the channel. This is true even for rather sharp bends. A significant amount of mode mixing is found, however, for bends with a small radius of curvature.
