We report a multifunctional device—making an object enlarge and rotate simultaneously via composite optical transformation. The potential application, i.e., a rotatable and high-directivity two-beam lens antenna, is investigated in detail. Full-wave finite element simulations for the two-dimensional cases are performed to demonstrate the properties of this device.
