The electron transmission through a system of two orthogonal quantum rings in a magnetic field with one input and two output wires is studied. It is shown that the transmission to only one of the two output leads can be governed by a change in the construction orientation in respect to the field. A model of nonplane quantum graph embedded in three-dimensional space is used.

磁场方向控制电子传输

研究了电子在一个输入和两个输出线的磁场中通过两个正交量子环系统的传输。结果表明，传输到两个输出引线中的只有一个可以通过相对于场的构造方向的变化来控制。使用嵌入三维空间的非平面量子图模型。
