Experimental demonstration of multiwire endoscopes capable of manipulating near-fields with subwavelength resolution

Abstract: Endoscopes formed by arrays of metallic wires can transmit, magnify, and demagnify near-field distributions with subwavelength resolution. Our experiments demonstrate that despite their small apertures, the parallel multiwire endoscopes can be used to transmit near-field distributions with a resolution of five thousandths of a wavelength to a distance of a half-wavelength in the microwave frequency range, and tapered multiwire endoscopes with flat input and output interfaces provide threefold image magnificati… Show more

“…A number of intriguing metamaterial devices have so far been demonstrated, including sub-diffraction-limited lenses [2,3], electromagnetic cloaks [4] negative refractive index materials [5], and perfectly absorbing materials [6]. Generally, metamaterial fabrication from the terahertz (THz) into the visible however relies on techniques that limit total sample sizes to be no larger than a few cm 2 , i.e.…”

“…We address the object plane with two facing fans of metallic tips in the spirit of the works by Belov's team [5][6][7][8][9][10][12][13][14][15][16][17][18][19], also termed endoscope [22] and sketched in planar form in Figs. 1(c) and 1(d).…”

“…In the case of "canalization," whose operation is more obvious, wires or tips carry free charges and transfer SWS fields along their surface [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], with a resolution limited by skindepth. There have been several studies to assess the degree of information transfer without mixing, and notably the perturbation caused by the change of impedance at the wire ends, making their length crucial in the abrupt-cut conditions.…”

“…Wire metamaterials have a number of unique properties [1], including the possibility of the subwavelength image transfer [2][3][4], negative refraction [5] and spontaneous emission time engineering [6]. Localized modes in the slabs of wire metamaterial have been studied previously in a number of papers [7,8], and it was shown that these modes are similar to the so-called spoof plasmons, a special class of surface modes, which propagate along corrugated metal or semiconductor surfaces [9][10][11].…”
