Subwavelength resolution for horizontal and vertical polarization by coupled arrays of oblate nanoellipsoids
arXiv:0901.1243 · doi:10.1364/OL.34.002333
Abstract
A structure comprising a coupled pair of two-dimensional arrays of oblate plasmonic nanoellipsoids in a dielectric host medium is proposed as a superlens in the optical domain for both horizontal and vertical polarizations. By means of simulations it is demonstrated that a structure formed by silver nanoellipsoids is capable of restoring subwavelength features of the object for both polarizations at distances larger than half-wavelength. The bandwidth of subwavelength resolution is in all cases very large (above 13%).
