A video simulation showing the cloaking of a system of three particles.
This video simulation shows the cloaking of a system of three particles. The dashed line is not a physical boundary, but marks the edge of the cloaking region. When the three particles are inside this region, they do not disturb the field outside, i.e., they are invisible from the outside.
