Enhanced modelling of split-ring resonators couplings in printed circuits
(Institute of Electrical and Electronics Engineers, 2014)
An enhanced equivalent circuit approach for the magnetic/electric interaction of single split-ring resonators (SRRs) with printed lines is presented in this paper. A very simple and efficient lumped-element network is ...

Extraordinary transmission through arrays of slits: A circuit theory model
(Institute of Electrical and Electronics Engineers, 2010)
Extraordinary transmission and other interesting related phenomena for 1-D periodic arrays of slits (compound diffraction gratings) have recently been the object of intense research in the optics and solid state physics ...
Article
Annular apertures in metallic screens as extraordinary transmission and frequency selective surface structures
(Institute of Electrical and Electronics Engineers, 2017)
A 2-D periodic array of annular apertures (or ring slots) is studied using an accurate circuit model. The model accounts for distributed and dynamic effects associated with the excitation of high-order modes operating above ...

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 ...

Analytical circuit model for 1-D periodic T-shaped corrugated surfaces
(Institute of Electrical and Electronics Engineers, 2014)
An analytical circuit model is obtained to study the reflection of TM polarized electromagnetic waves that impinge obliquely on a 1-D periodic corrugated surface consisting of dielectric-loaded T-shaped planar corrugations ...

Resonant Modes of a Waveguide Iris Discontinuity: Interpretation in Terms of Canonical Circuits
(Institute of Electrical and Electronics Engineers, 2018)
This paper presents an eigenproblem for computing the resonances of multiresonant irislike discontinuities in waveguides. The formulation of the eigenproblem is based on integral equation methods, and its solution provides ...

Compact balanced FSIR bandpass filter modified for enhancing common-mode suppression
(Institute of Electrical and Electronics Engineers, 2015)
A novel balanced bandpass filter (BPF) based on folded stepped impedance resonators (FSIR's) with modified ground plane is presented in this work. By symmetrically introducing a series-LC resonant structure below the FSIR's, ...

Study of extraordinary transmission in a circular waveguide system
(Institute of Electrical and Electronics Engineers, 2010)
Extraordinary transmission through periodic distributions of sub-wavelength holes made in opaque screens has been demonstrated and exhaustively studied along the last decade. More recently, extraordinary transmission has ...

Computationally efficient analysis of extraordinary optical transmission through infinite and truncated subwavelength hole arrays
(American Physical Society, 2016)
The authors present a computationally efficient technique for the analysis of extraordinary transmission through both infinite and truncated periodic arrays of slots in perfect conductor screens of negligible thickness. ...

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 ...
