基于坐标变换和保角映射方法，设计了一种具有放大倍数的亚波长成像装置，称为“平面超透镜”，能够实现远场超越衍射极限的平面对平面成像。提出了利用由金属薄层和介电薄层交替形成的有效各向异性超材料实现的可能方法。对设计的多层透镜结构的放大性能进行了数值模拟，验证了理论分析的正确性。
Based on coordinate transformation incorporated with conformal mapping approach, a sub-wavelength imaging device with magnification, called "planar hyperlens" is designed, capable of realizing far-field plane-to-plane imaging beyond the diffraction limit. The possible implementation method is proposed by using effective anisotropic metamaterial formed by alternating metallic and dielectric thin layers. The magnification performance of the designed multi-layer lensing structure is numerically simulated to confirm our theoretical analysis.
