Resolving subwavelength objects with a crossed wire mesh superlens operated in backscattering mode
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...
متن کاملSome problems with negative refraction.
Some Problems with Negative Refraction* by John Michael Williams P. O. Box 2697, Redwood City, CA 94064 [email protected] Abstract J. B. Pendry's "Negative Refraction Makes a Perfect Lens" is analyzed. It appears that several statements may be understood in terms of lens design but not in terms of fundamental behavior of light. In a recent Letter, "Negative Refraction Makes a Perfect Lens" (P...
متن کاملThree-dimensional nanotransmission lines at optical frequencies: A recipe for broadband negative-refraction optical metamaterials
We apply the optical nanocircuit concepts to design and analyze in detail a three-dimensional (3D) plasmonic nanotransmission line network that may act as a relatively broadband negative-refraction metamaterial at infrared and optical frequencies. After discussing the heuristic concepts in our theory, we show full-wave analytical results of the expected behavior of such materials, which show in...
متن کاملOptical negative refraction in ferrofluids with magnetocontrollability.
We numerically demonstrate optical negative refraction in ferrofluids containing isotropic Fe3O4 nanoparticles, each having an isotropic Ag shell, in the presence of an external dc magnetic field H. The all-angle broadband optical negative refraction with magnetocontrollability arises from H-induced chains or columns. They result in hyperbolic equifrequency contour for transverse magnetic waves...
متن کاملIsotropic microwave composites with negative refraction
The properties of artificial isotropic microwave composites which would possess simultaneously negative permittivity and permeability are studied theoretically. Four kinds of composites are considered. Two of them concern media with split-ring resonator particles with different particle arrangements. The other two are realized with Omega particles. An analytical antenna model of the electromagn...
