多线内窥镜可以在亚波长尺度上操纵电磁场。最近，已经提出了这种设备的两种不同配置。在这里，我们比较了Belov等人介绍的成像设备的成像性能。[物理。修订本B 73,033108(2006年)]和Silveirinha等人。[物理。Rev.B75,035108(2007年)]使用Shvets等人描述的屏蔽多线内窥镜。[物理。莱特牧师。99,053903(2007年)]。研究表明，后者的性能可能受到内窥镜周围金属屏蔽层的存在以及内窥镜与自由空间之间不匹配的严重影响。我们的结果表明，金属屏蔽是完全不必要的，并强调了根据Belov等人提出的Fabry-Perot共振条件来调整导线长度的重要性。[物理。修订本B 73,033108(2006年)]。
Multiwire endoscopes may enable the manipulation of the electromagnetic field in the subwavelength scale. Recently, two different configurations of such devices have been proposed. Here, we compare the imaging performance of the imaging device introduced by Belov et al. [Phys. Rev. B 73, 033108 (2006)] and by Silveirinha et al. [Phys. Rev. B 75, 035108 (2007)] with the shielded multiwire endoscope described by Shvets et al. [Phys. Rev. Lett. 99, 053903 (2007)]. It is demonstrated that the performance of the latter may be strongly affected by the presence of a metallic shield around the endoscope and by poor matching between the endoscope and free space. Our results show that the metallic shield is completely unnecessary and emphasize the importance of tuning the length of the wires according to the Fabry–Perot resonance condition, as proposed by Belov et al. [Phys. Rev. B 73, 033108 (2006)].
