Design of a dual band-pass filter using modified folded stepped-impedance resonators
(Institute of Electrical and Electronics Engineers, 2009)
A folded stepped impedance resonator (SIR) modified by adding an inner quasi-lumped SIR stub is used as the basic block of a new configuration of dual band-pass filter. The main advantage of the proposed filter is to allow ...

Multi-band high-impedance surface absorbers with a single resistive sheet: Circuit theory model
(Institute of Electrical and Electronics Engineers, 2011)
We present a simple and efficient circuit model for the analysis of multi-band absorption characteristics of a stack of sub-wavelength grids (fishnets or patch arrays) in a layered environment with a single resistive sheet ...

Equivalent circuits for conventional and extraordinary reflection in dipole arrays
(Institute of Electrical and Electronics Engineers, 2011)
This presents an equivalent transmission-line circuit that accounts for the scattering of a TE polarized plane wave that impinges obliquely on a periodic array of metallic patches sandwiched in a dielectric slab. The ...

Analytical circuit model for stacked slit gratings
(Institute of Electrical and Electronics Engineers, 2014)
This work presents a rigorous circuit model to compute the transmission/reflection properties of a finite number of stacked slit gratings printed on dielectric slabs of arbitrary thickness. A key aspect of the present ...

Split rings-based differential transmission lines with common-mode suppression
(Institute of Electrical and Electronics Engineers, 2011)
A novel microstrip differential transmission line with common-mode noise suppression is proposed and experimentally validated. It is implemented by periodically etching complementary split ring resonators (CSRRs) in the ...

Low-terahertz transmissivity with a graphene-dielectric micro-structure
(Institute of Electrical and Electronics Engineers, 2012)
In this paper, we report on the analysis of transmissivity of electromagnetic waves through a stack of dielectric slabs loaded with atomically thin graphene sheets at low-terahertz frequencies. It is observed that the ...

Generalized additional boundary conditions and analytical model for multilayered mushroom-type wideband absorbers
(Institute of Electrical and Electronics Engineers, 2012)
We present an analytical model to study the reflection properties of a multilayered wire media loaded with 2-D arrays of thin imperfect conductors. Based on charge conservation, generalized additional boundary conditions ...

Analytical circuit model for dipole frequency-selective surfaces
(Institute of Electrical and Electronics Engineers, 2013)
This contribution provides a fully analytical transmission-line circuit model for the transmission/reflection of an obliquely incident plane wave by a periodic array of printed dipoles. The topology of the equivalent circuit ...

Fully analytical circuit-like approach for the TE scattering by narrow-slit printed gratings
(Institute of Electrical and Electronics Engineers, 2012)
A fully analytical solution for the scattering of a uniform TE polarized plane wave by an infinite periodic printed array of narrow slits is provided in this contribution. The model is based on some simplifications made ...

Equivalent circuit model to explain extraordinary transmission
(Institute of Electrical and Electronics Engineers, 2008)
This work proposes a circuit model based explanation for the extraordinary transmission (ET) of light phenomenon studied in recent scientific literature [1], [2]. ET mainly stands for unexpected transmission of light through ...
