Analytical Multimodal Network Approach for 2-D Arrays of Planar Patches/Apertures Embedded in a Layered Medium
(Institute of Electrical and Electronics Engineers, 2015)
A fully analytical multimodal equivalent circuit is presented for the modeling of the scattering of an obliquely incident plane wave by a two-dimensional (2-D) periodic array of metallic patches (or apertures in a metallic ...

Enhanced transmission with a graphene-dielectric microstructure at low-terahertz frequencies
(American Physical Society, 2012)
Here, we report on the transmissivity of electromagnetic waves through a stack of monolayer graphene sheets separated by dielectric slabs at low-terahertz frequencies. It is observed that the multilayer structure possesses ...

Periodic arrangements of chiral scatterers providing negative refractive index bi-isotropic media
(American Physical Society, 2008)
The main goal of this contribution is to show that periodic arrangements of chiral scatterers can be the basis for the development of three dimensional and isotropic negative refractive index artificial media. Three ...

Three-dimensional superresolution in metamaterial slab lenses: Experiment and theory
(American Physical Society, 2005)
This paper presents a theoretical and experimental study on the viability of obtaining two- and three-dimensional superresolution (i.e., resolution overcoming the diffraction limit for all directions in space) by means of ...

Extraordinary transmission through arrays of electrically small holes from a circuit theory perspective
(Institute of Electrical and Electronics Engineers, 2008)
Extraordinary optical transmission of light or electromagnetic waves through metal plates periodically perforated with subwavelength holes has been exhaustively analyzed in the last ten years. The study of this phenomenon ...

Circuit modeling of multiband high-impedance surface absorbers in the microwave regime
(American Physical Society, 2011)
In this paper, we present a simple circuit model to study the absorption of electromagnetic waves by a multilayer structure with a high impedance surface in the microwave regime. The absorber consists of a stack of ...

Circuit model for a periodic array of slits sandwiched between two dielectric slabs
(American Institute of Physics, 2010)
This paper proposes an equivalent circuit model that uses lumped elements and transmission lines to explain the transmission of electromagnetic waves through a conducting screen periodically perforated with slits and ...
