我们提出并分析了一种创新的设备，称为“混合超级超透镜”。该透镜由两种介电张量符号不同、等效色散曲线不同的双曲型超材料组成。所提出的透镜的能力，以打破光学衍射极限的数值模拟证明（与约λ/6的分辨率）。该透镜利用径向偏振光源可以对一对纳米狭缝和一个纳米环进行成像和分辨。这种透镜在光刻和实时纳米成像中具有巨大的潜在应用。(C)2013年美国光学学会
We propose and analyze an innovative device called "Hybrid-Super-Hyperlens". This lens is made of two hyperbolic metamaterials with different signs in their dielectric tensor and different isofrequency dispersion curves. The ability of the proposed lens to break the optical diffraction limit is demonstrated using numerical simulations (with the resolution power of about lambda/6). Both a pair of nano-slits and a nano-ring can be imaged and resolved by the proposed lens using the radially polarized light source. Such a lens has great potential applications in photolithography and real-time nanoscale imaging. (C) 2013 Optical Society of America
