On the use of SDA for the analysis of boxed planar lines with complex media
(Institute of Electrical and Electronics Engineers, 2001)
This paper discusses the conditions under which the spectral-domain approach (SDA) can be applied to the analysis of boxed planar lines when complex materials (anisotropic dielectrics, ferrites, magnetoplasmons, chiral ...

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 ...

Near-field enhanced imaging by a magnetized ferrite slab
(American Institute of Physics, 2005)
This letter demonstrates the near-field imaging enhancement at microwave frequencies of two-dimensional sources by a ferrite slab magnetized to saturation. It is shown that this effect is based on the nonreciprocal ...

Differential Lines for Common-Mode Suppression Based in Hybrid Microstrip/CPW Technology
(Institute of Electrical and Electronics Engineers, 2017)
A symmetrical pair of differential microstrip lines implemented in hybrid microstrip/coplanar waveguide (CPW) technology is proposed. Transmission-line models are used to analyze differential-and common-mode responses, ...

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 ...

Numerical implementation of the mixed potential integral equation for planar structures with ferrite layers arbitrarily magnetized
(Wiley-Blackwell, 2006)
This work presents a new implementation of the mixed potential integral equation (MPIE) for planar structures that can include ferrite layers arbitrarily magnetized. The implementation of the MPIE here reported is carried ...

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 ...

Quasi-TEM analysis of multilayered, multiconductor coplanar structures with dielectric and magnetic anisotropy including substrate losses
(Institute of Electrical and Electronics Engineers, 1990)
A quasi-TEM (transverse electromagnetic) analysis of multiconductor planar lines embedded in a layered structure involving lossy iso/anisotropic electric and/or magnetic materials is achieved. Conditions under which a ...

On the Quasi-TEM and Full-Wave Approaches Applied to Coplanar Multistrip on Lossy Dielectric Layered Media
(Institute of Electrical and Electronics Engineers, 1992)
The characteristic parameters of coplanar multistrip lines embedded in multilayered lossless/lossy substrates are commonly computed by using either quasi-TEM or full-wave models. Several methods are provided in the literature ...

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. ...
