The detonation propagation in a channel geometry which suppresses detonation propagation in one direction, allows it in another direction, and does not create flow restrictions in the channel. The geometry consists of a series of divergent sections separated by wedges that form a sawtooth shape. The detonation fails to propagate through this geometry in one direction because the detonation front is weakened by diffraction, and reignition centers are isolated from the main channel. In an opposite direction, convergent parts of the geometry support the detonation propagation, because subsequent shock collisions with oblique walls that form convergent sections create powerful transverse waves. These powerful transverse waves help the detonation propagation or reignite it.
