Metallo-dielectric core-shell nanospheres as building blocks for optical three-dimensional isotropic negative-index metamaterials
(Institute of Physics Publishing, 2011)
Materials showing electromagnetic properties that are not attainable in naturally occurring media, so-called metamaterials, have been lately, and still are, among the most active topics in optical and materials physics and ...

Transmission through stacked 2D periodic distributions of square conducting patches
(American Institute of Physics, 2012)
In this paper, we study the transmissivity of electromagnetic waves through stacked two-dimensional printed periodic arrays of square conducting patches. An analytical circuit-like model is used for the analysis. The model ...

Combining DC and AC electric fields with deterministic lateral displacement for micro- And nano-particle separation
(American Institute of Physics, 2019)
This paper describes the behavior of particles in a deterministic lateral displacement (DLD) separation device with DC and AC electric fields applied orthogonal to the fluid flow. As proof of principle, we demonstrate ...

Broadband Extraordinary Transmission in a single sub-wavelength aperture
(Optical Society of America, 2010)
Coordinate transformation is applied to design an all-dielectric device for Extraordinary Transmission (ET) in a single sub-wavelength slit. The proposed device has a broadband feature and can be applied from microwave to ...

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 ...

Analytical model for the transmission of electromagnetic waves through arrays of slits in perfect conductors and lossy metal screens
(American Institute of Physics, 2011)
This paper presents a very simple analytical model for the analysis of the resonant transmission of microwaves or millimeter waves through periodically distributed slits in a thick metal screen. The model is based on ...

Signal-to-noise ratio evaluation in resonant ring metamaterial lenses for MRI applications
(IOP Publishing Ltd., 2011)
In this paper, we present a method for the evaluation of the signalto- noise ratio in magnetic resonance imaging (MRI) coils loaded with resonant ring metamaterial lenses, in the presence of a conducting phantom resembling ...

Simplified single-phase clock scheme for MOBILE networks
(Institute of Electrical and Electronics Engineers, 2011)
MOBILE networks can be operated in a gate-level pipelined fashion allowing high through-output. If MOBILE gates are directly chained, a four-phase clock scheme is required for this. A single-phase scheme is possible adding ...

Dual capacitive-inductive nature of periodic graphene patches: Transmission characteristics at low-terahertz frequencies
(American Physical Society, 2013)
We report on the dual nature (capacitive and inductive) of the surface impedance of periodic graphene patches at low-terahertz frequencies. The transmission spectra of a graphene-dielectric stack shows that patterned ...
