Serial title, monograph or event: | New Journal of Physics | Volume: | 13 | Issue: | 5 | Abstract: | In this work, we demonstrate that a crossed-wires superlens operated in backscattering mode can resolve targets separated by a subwavelength distance. It is theoretically shown that the effect of the backscattered field on the return loss of a probe antenna is sufficiently strong to allow us to discriminate the targets over a broad range of frequencies. These properties have been experimentally confirmed at microwave frequencies. | URI: | https://hdl.handle.net/10316/110047 | ISSN: | 1367-2630 | DOI: | 10.1088/1367-2630/13/5/053004 | Rights: | openAccess |
