We report on the fabrication of two types of adjustable, near-field superlens designs: metal–dielectric composites and metal–dielectric multilayer films. We fabricated a variety of films with different materials, thicknesses and compositions. These samples were characterized physically and optically to determine their film composition, quality, and optical responses. Our results on metal–dielectric composites indicate that although the real part of the effective permittivity generally follows… 
Conformable optical coatings with epsilon near zero response
We design and experimentally demonstrate an optical free-standing and low-loss metamaterial showing a vanishing effective permittivity. The material consists of a stack of subwavelength polymer and
Optical properties of metal-dielectric based epsilon near zero metamaterials
We demonstrate epsilon near zero (ENZ) metamaterials operating at visible wavelengths near 660 nm. The structure consists of a multilayer stack composite of alternating layers of Ag and TiO2, 16 nm
On the dielectric function tuning of random metal-dielectric nanocomposites for metamaterial applications.
This result suggests that a random mixture consisting of a metal matrix with embedded isolated dielectric inclusions is a promising design guideline for the fabrication of tunable composites for metamaterial purposes.
Analysis and design of a multilayer plasmonic superlens by complex images technique
A superlens is a slab of metal sandwiched between two dielectric layers. This structure can produce the image of an object in close vicinity without suffering from diffraction limit. Better
Tunable surface plasmon polaritons in Ag composite films by adding dielectrics or semiconductors
We demonstrate that the surface plasmon polariton (SPP) properties of the silver composite films can be tuned by modest additions of silicon oxide or silicon. The dispersion relations deviate from
Dispersion engineering for surface waves on multilayer metal-insulator stacks
A multilayer metal-insulator (MMI) stack system is viewed as an anisotropic metamaterial to exhibit plasmonic behavior and a candidate of "metametal". The dispersion of the fundamental super mode
Tunable Multilayer Plasmonic Materials: Optical and Topographic Characterizations
The distinct behavior of structures of noble metals with nano-dimensions from that of the bulk metal in visible electromagnetic spectrum has provided access to exquisite characteristics and
High resolution photolithography with sub-wavelength grating
Based on the theory of surface plasmon resonance and the special nano-optical effect of metal/dielectric multilayer composites, we obtained a high-resolution image of a sub-wavelength grating. We
Studies of plasmonic hot-spot translation by a metal-dielectric layered superlens
We have studied the ability of a lamellar near-field superlens to transfer an enhanced electromagnetic field to the far side of the lens. In this work, we have experimentally and numerically
Permittivity evaluation of multilayered hyperbolic metamaterials: Ellipsometry vs. reflectometry
Metal-dielectric nanolaminates represent a class of hyperbolic metamaterials with uniaxial permittivity tensor. In this study, we critically compare permittivity extraction of nanolaminate samples


Superlens based on metal-dielectric composites
Pure noble metals are typically considered to be the materials of choice for a near-field superlens that allows subwavelength resolution by recovering both propagating and evanescent waves. However,
Superlens from metal-dielectric composites of nonspherical particles
A tunable near-field superlens (NFSL) from metal-dielectric composites has advantages over that one from bulk metal. In this paper, we realize the tunable NFSL by tuning the shape of granular
Thin film Ag superlens towards lab-on-a-chip integration.
A thin metal film near-field superlens, as originally suggested by Pendry and realized by Fang et al. and Melville et al., is investigated with emphasis on materials suitable for integration on a
Directed subwavelength imaging using a layered metal-dielectric system
We examine some of the optical properties of a metamaterial consisting of thin layers of alternating metal and dielectric. We can model this material as a homogeneous effective medium with
Translation of nanoantenna hot spots by a metal-dielectric composite superlens
We employ numerical simulations to show that highly localized, enhanced electromagnetic fields, also known as “hot spots,” produced by a periodic array of silver nanoantennas can be spatially
Sub–Diffraction-Limited Optical Imaging with a Silver Superlens
This work demonstrated sub–diffraction-limited imaging with 60-nanometer half-pitch resolution, or one-sixth of the illumination wavelength, using silver as a natural optical superlens and showed that arbitrary nanostructures can be imaged with good fidelity.
Negative refractive index in optics of metal-dielectric composites
Specially designed metal-dielectric composites can have a negative refractive index in the optical range. Specifically, it is shown that arrays of single and paired nanorods can provide such negative
Molecular Scale Imaging with a Multilayer Superlens
It has been experimentally demonstrated that a single layer of silver functions as a “superlens” [Fang et al, Science 308, 534 (2005)], providing image resolution much better than the diffraction

Experimental confirmation that super-resolution imaging can be achieved using a 50-nm thick planar silver layer as a near-field lens at wavelengths around 365 nm agrees well with finite-difference time domain (FDTD) simulations.
