We describe the change of the spatial distribution of the state of polarization occurring during two-dimensional (2D) imaging through a multilayer and in particular through a layered metallic flat lens. Linear or circular polarization of incident light is not preserved due to the difference in the amplitude transfer functions for the TM and TE polarizations. In effect, the transfer function and the point spread function (PSF) that characterize 2D imaging through a multilayer both have a matrix…

Analysis of a Plane Wave-Excited Subwavelength Circular Aperture in a Planar Conducting Screen Illuminating a Multilayer Uniaxial Sample

A spectral domain analysis is presented of a plane wave-excited subwavelength circular aperture in a planar perfectly conducting screen in close proximity to a multilayer stack, which may comprise

Two-dimensional imaging in hyperbolic media–the role of field components and ordinary waves

TLDR
This work adapts the exact transfer matrix method for uniaxial media to calculate the two dimensional transfer functions and point spread functions for arbitrary vector fields described in Cartesian coordinates, more convenient for imaging simulations than the use of the natural, propagation direction-dependent TE/TM basis.

We propose to use the blind deconvolution and its modification to extract the point spread function (PSF) of layered metamaterials from a SNOM measurement. The measurement results are processed using

Fourier optics approach to imaging with sub-wavelength resolution through metal-dielectric multilayers

Metal-dielectric layered stacks for imaging with sub-wavelength resolution are regarded as linear isoplanatic systems — a concept popular in Fourier optics and in scalar diffraction theory. In this

Image fidelity for single-layer and multi-layer silver superlenses.

TLDR
It is shown that increasing the number of layers in a lens increases the lens' transmission coefficients at high spatial frequencies; however, this does not always lead to better imaging performance, and the design of the superresolving lens system should take into account the characteristics of the images that it is expected to transmit.

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

Spatially engineered polarization states and optical vortices in uniaxial crystals.

TLDR
Under cylindrically symmetric light-matter interaction, the radially, azimuthally, and spirally polarized eigen-modes for the light field are revealed to be of a fundamental interest to describe the physical mechanisms at work when dealing with scalar and vectorial optical singularities.

Multiscale analysis of subwavelength imaging with metal-dielectric multilayers.

TLDR
It is shown that in the same optical system the image of a narrow subwavelength Gaussian incident field may be surprisingly dissimilar to thePSF, and the width of the PSF is not a straightforward measure of the resolution.

Super-resolution imaging through a planar silver layer.

TLDR
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.

Transmission function properties for multi-layered structures: application to super-resolution.

TLDR
It is analytically demonstrated that a transmission greater than one in the evanescent spectrum (amplification of the Evanescent modes) can be directly linked to the guided modes supported by the structure.

The asymmetric lossy near-perfect lens

We extend the ideas of the perfect lens recently proposed [J.B. Pendry, Phys. Rev. Lett. 85, 3966 (2000)] to an alternative structure. We show that a slab of a medium with negative refractive index
