Experimental setup of the random anti-laser (click for more info).
Experimental setup of the random anti-laser: a waveguide contains a disordered medium consisting of a set of randomly placed Teflon cylinders, at which incoming microwave signals are scattered in a complex manner. In the top plate of the waveguide (moved aside for illustrative purposes) a central antenna is installed, which absorbs the microwaves. Image: TUV.
