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–Pérot resonance condition, as proposed by Belov et al. Phys. Rev. B 73, 033108 2006.
