摘要：

We present the demonstration of a bifunctional metasurface in the microwave regime. The metasurface is composed of periodically arranged anisotropic elements, with various electromagnetic responses according to polarizations of incident waves. When the metasurface is wrapped on a moderately sized metallic cylinder, we show that it acts as an illusion coating for one polarization but a mantle cloak for another polarization. Numerical simulations have been carried out to demonstrate the illusion and cloaking properties of the metasurface, which open up new and intriguing applications in multifunctional metadevices.
