Magnetic 'invisibility cloak' hides obstacles within particle streams

Researchers at the University of Bayreuth have developed a method that makes objects on a magnetic field invisible within a particle stream. Until now, this so-called cloaking had only been studied for waves such as light or sound. They report their results in Nature Communications.

Scientists from the University of Bayreuth have developed a technology that makes objects invisible in a particle flow using a magnetic field. For the first time, a cloaking technique previously used only to control light and sound waves has been successfully adapted to influence the movement of particles. A research team led by specialists from the Department of Experimental and Theoretical Physics has created a system in which colloid particle…
