The electron beam that direction is propagated and the electromagnetic wave propagated along folded waveguide are under the conditions of the speed sync of Z-direction, at same period
In two interaction regions in, suffered by electron beam along Z-direction active force can switching direction, cause electromagnetic wave from electricity
The energy that son bundle obtains is cancelled out each other.In order to solve this problem, electron beam is along speed and the electromagnetic wave of Z-direction along Z-direction
