Problems solved by technology

[0003] Commonly used plane wave generators include plane wave lenses, mouse clip plane wave generators and network board plane wave generators. The plane wave lens is composed of low detonation velocity and high detonation velocity explosives, the inner layer is a cone of low detonation velocity explosives, and the outer layer is high detonation velocity explosives The frustum of the cone, through the control of the interface of the two explosives, makes the detonation waves at different distances from the center point reach the interface at the same time, and output the plane shock wave. The diameter of the commonly used plane wave lens is and In general, within 90% of the size range from the center of the drug layer, the wavefront unevenness of the plane wave lens is less than 0.15μs. The disadvantage of this type of plane wave generator is that the size is generally large and the manufacturing cost is high.
