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\u200873, 033108 (2006)] and by Silveirinha et al. [Phys. Rev. B\u200875, 035108 (2007)] with the shielded multiwire endoscope described by Shvets et al. [Phys. Rev. Lett.\u200899, 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\u2013P\u00e9rot resonance condition, as proposed by Belov et al. [Phys. Rev. B\u200873, 033108 (2006)].<\/jats:p>","DOI":"10.1063\/1.3073714","type":"journal-article","created":{"date-parts":[[2009,1,23]],"date-time":"2009-01-23T14:23:57Z","timestamp":1232720637000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":16,"title":["The importance of Fabry\u2013P\u00e9rot resonance and the role of shielding in subwavelength imaging performance of multiwire endoscopes"],"prefix":"10.1063","volume":"94","author":[{"given":"Atiqur","family":"Rahman","sequence":"first","affiliation":[{"name":"Queen Mary University of London 1 Department of Electronic Engineering, , Mile End Road, London E1 4NS, United Kingdom"}]},{"given":"Pavel A.","family":"Belov","sequence":"additional","affiliation":[{"name":"Queen Mary University of London 1 Department of Electronic Engineering, , Mile End Road, London E1 4NS, United Kingdom"}]},{"given":"M\u00e1rio G.","family":"Silveirinha","sequence":"additional","affiliation":[{"name":"Universidade de Coimbra 2 Instituto de Telecomunica\u00e7\u00f5es, , 3030 Coimbra, Portugal"}]},{"given":"Constantin R.","family":"Simovski","sequence":"additional","affiliation":[{"name":"Helsinki University of Technology 3 Radio Lab., , P.O.
