摘要：

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.
