title: Experimental realization of a circuit-based broadband illusion-optics analogue.
abstract: We experimentally demonstrate the first metamaterial "illusion optics" device--an "invisible gateway" by using a transmission-line medium. The device contains an open channel that can block waves at a particular frequency range. We also demonstrate that such a device can work in a broad frequency range.
