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 ...

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 ...

Simplified Modal Expansion to Analyze Frequency-Selective Surfaces: An Equivalent Circuit Approach
(Institute of Electrical and Electronics Engineers, 2016)
This communication extends a previously reported analytical circuit that models the plane wave scattering by 2-D arrays of planar patches/apertures embedded in a layered media. In this extension, it is assumed that the ...

Some advances in the circuit modeling of extraordinary optical transmission
(Brno University of Technology, 2009)
The phenomenon of extraordinary optical transmission (EOT) through electrically small holes perforated on opaque metal screens has been a hot topic in the optics community for more than one decade. This experimentally ...

Accurate circuit modeling of fishnet structures for negative-index-medium applications
(Institute of Electrical and Electronics Engineers, 2016)
Metallic plates with a two-dimensional (2D) periodic distribution of sub-wavelength apertures are known to exhibit extraordinary transmission of electromagnetic waves. Stacking two or more of such plates gives place to 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 ...

Analytical wideband model for strip/slit gratings loaded with dielectric slabs
(Institute of Electrical and Electronics Engineers, 2012)
This paper presents a fully analytical model to determine the transmission and reflection properties of planar 1-D distributions of metal strips or slits made in thin metal screens. In contrast with other analytical or ...

Enhanced Implementation of the Complex Images Method to Study Bound and Leaky Regimes in Layered Planar Printed Lines
(Institute of Electrical and Electronics Engineers, 2004)
The discrete complex image technique, originally developed to deal with three-dimensional planar structures, has been recently applied to two-dimensional planar and nonplanar transmission lines embedded in layered substrates. ...

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 ...

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 ...
