提出了一种新的光学超透镜的设计方法，用于远场亚衍射极限物体的成像。我们的超透镜是由金属纳米圆柱嵌入在电介质中，导致人工各向异性光学超材料。各向异性的有效介电常数出现由于金属纳米柱的谐振行为。我们提出的数值计算结果说明了光学超透镜组成的银纳米柱在石英玻璃。
We present a novel design for an optical hyperlens to image sub-diffraction limited objects in the far field. Our hyperlens is composed of metallic nanocylinders embedded in a dielectric medium, resulting in an artificially anisotropic optical metamaterial. The anisotropic effective permittivity emerges due to the resonant behaviour of metallic nanocylinders. We present numerical results illustrating an optical hyperlens composed of silver nanocylinders in silica glass.
