At t = 0 s, the two particles are placed at the preset levitation point. The initial spatial position coordinates are (53.7, 87, 100) and (92.6, 87, 100) respectively. When t = 2 s, the left particle is manipulated to move toward the right particle. At t = 18.3 s, the distance between the two particles is about 1.2λ (10.4 mm). When the left particle is manipulated to move to the right particle, the left particle can no longer move completely according to the preset levitation point, while the position of the right preset levitation point remains unchanged, but the actual position has begun to move to the right, and the two particles cannot come together.
