Illustration and photograph of system setup.

The size of system is 520(height)×520 mm(width)×250 mm(depth). The focal point is set in the center of workspace. The labels of axis are shown in the figure: x-axis and z-axis are parallel to the device plane and y-axis is vertical to the device plane. We inserted the particles at the third node of beams that is parallel to x-axis in the stability experiments.
