| Abstract: | Based on theory of optical transformation, a novel rotatable and amplifying optical transformation device was proposed, and this device could be realized with metamaterials with parameters of positive refraction index. The constitutive tensors of the proposed device were derived, and then some full wave simulations of the devices based on the above constitutive tensor were performed to confirm the functionality of the proposed device. The simulations results verified that the proposed device can make the inside object rotate and enlarge. Therefore, it is expected that the proposed device will have potential applications in the electromagnetic engineering. |
