介绍了一种基于广义拟共形映射方法的三维变换光学(TO)介质的设计方法。广义准共形TO(QCTO)方法可以设计出原则上宽带和低损耗的介质，同时控制具有任意入射角和偏振角的波的传播。我们举例说明了三维地毯地平面斗篷和平面型伦堡透镜的设计方法。光线跟踪研究证实了QCTO介质的性能，同时也揭示了这些设备的仅索引版本的有限性能。
We introduce an approach to the design of three-dimensional transformation optical (TO) media based on a generalized quasiconformal mapping approach. The generalized quasiconformal TO (QCTO) approach enables the design of media that can, in principle, be broadband and low loss, while controlling the propagation of waves with arbitrary angles of incidence and polarization. We illustrate the method in the design of a three-dimensional carpet ground plane cloak and of a flattened Luneburg lens. Ray-trace studies provide a confirmation of the performance of the QCTO media, while also revealing the limited performance of index-only versions of these devices.
