我们表明，通过磁势垒结构的传输的角度范围可以有效地控制在单层和双层石墨烯，这使得该结构的有效的波矢量滤波器。随着磁垒数量的增加，这个范围缩小，透射率与能量的差距变得更宽，电导随着费米能量而振荡。
We show that the angular range of the transmission through magnetic barrier structures can be efficiently controlled in single-layer and bilayer graphenes and this renders the structure's efficient wavevector filters. As the number of magnetic barriers increases, this range shrinks, the gaps in the transmission versus energy become wider, and the conductance oscillates with the Fermi energy.
