Wideband analytical equivalent circuit for coupled asymmetrical nonaligned slit arrays
(American Physical Society, 2017)
Microstructured metallic devices have been extensively studied because of their interesting properties for controlling the transmission, reflection, and absorption of electromagnetic waves. A very simple implementation is ...

Analytical theory of wave propagation through stacked fishnet metamaterials
(Optical Society of America, 2009)
This work analyzes the electromagnetic wave propagation through periodically stacked fishnets from zero frequency to the first Wood's anomaly. It is shown that, apart from Fabry-Perot resonances, these structures support ...

Experimental verification of extraordinary transmission without surface plasmons
(American Institute of Physics, 2009)
This letter provides an experimental demonstration of extraordinary transmission in a closed waveguide system loaded with an electrically small diaphragm. This is a situation where the standard surface plasmon polariton ...

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 ...

Making metals transparent: A circuit model approach
(The Optical Society, 2016)
Solid metal films are well known to be opaque to electromagnetic waves over a wide frequency range, from low frequency to optics. High values of the conductivity at relatively low frequencies or negative values of the ...

Physically-insightful equivalent circuit models for electromagnetic periodic structures
(IOP Publishing Ltd., 2018)
In this presentation it will be discussed how to obtain analytical or quasi-analytical equivalent circuits to deal with periodic structures such as frequency selective surfaces and/or metasurfaces. Both the topology and ...

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 ...

Wideband analytical equivalent circuit for one-dimensional periodic stacked arrays
(American Physical Society, 2016)
A wideband equivalent circuit is proposed for the accurate analysis of scattering from a set of stacked slit gratings illuminated by a plane wave with transverse magnetic or electric polarization that impinges normally or ...

Microstrip circuit analog of a complex diffraction phenomenon
(American Institute of Physics, 2009)
This letter presents a methodology to reproduce at microwave frequencies the physical behavior of certain diffraction structures that have been investigated in the optics community. The methodology will be exemplified with ...
