A cylindrical cloak can be interpreted as a controlled mirage upon a transformation from cylindrical to planar stratified layers. Here, we show that such mirage can be obtained using a pseudomagnetic field instead of a gradient index profile, thus enabling an alternative route towards invisibility cloaking. While working equivalently to a conventional cloak, the asymmetry of light bending direction from a pseudomagnetic field enables the cloak to demonstrate an asymmetric transmission property subject to a truncation of the materials near the inner surface of the cloak. Furthermore, such an asymmetry allows us to design transformation optical devices, such as a one-way retroreflector, with asymmetric transmission.
