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.

Thanks to illusion optics, an open channel across a metamaterial slab is made invisible to light incident from the left.
