在现实中，具有复杂的、连续的电磁参数的光学变换介质很难实现。在这项工作中，我们提出了一种离散嵌入光学变换，并在此基础上设计了一种分层高增益透镜天线。透镜天线的所有层都由均匀的单轴各向异性超材料组成，结构简单，可实现性强。当分层透镜嵌入喇叭天线时，透镜天线提供高方向性辐射波束。利用离散光学变换设计了一种多波束高增益天线。
In reality, the optical-transformation media with complicated and continuous electromagnetic parameters are difficult to realize. In this work, we propose a discrete embedded optical transformation from which a layered high-gain lens antenna is designed. All layers of the lens antenna are composed of homogeneous and uniaxially anisotropic metamaterials, which are simple and realizable. When the layered lens is embedded in a horn antenna, the lens antenna provides a high-directivity radiation beam. We also use the discrete optical transformation to design a multibeam high-gain antenna.
