Cloaking using a volumetric structure composed of stacked two-dimensional transmission-line networks is verified with numerical simulations and measurements. The measurements are done in a waveguide, in which an array of metal cylinders is inserted causing a short circuit in the waveguide. The metal cylinders are cloaked using the transmission-line structure, which “hides” the cylinders and thus enables wave propagation inside the waveguide.

    Numerical simulations of galaxy clusters have advanced over time to the point where a large number of physical processes can be accurately captured. However, in order to accurately constrain the role of each process in cluster evolution, we must carefully compare with observational data. While...
