Roadmap on metasurfaces
(IOP Publishing, 2019)
Metasurfaces are thin two-dimensional metamaterial layers that allow or inhibit the propagation of electromagnetic waves in desired directions. For example, metasurfaces have been demonstrated to produce unusual scattering ...

Generalized Spectral Analysis of Planar Lines on Layered Media Including Uniaxial and Biaxial Dielectric Substrates
(Institute of Electrical and Electronics Engineers, 1989)
In this paper the spectral-domain analysis (SDA) is generalized in order to compute the dispersive properties of a wide variety of planar and quasi-planar transmission lines (microstrips and finlines) printed on a stratified ...

Two-dimensional study of leaky modes in microstrip line with a semi-infinite cover layer
(Wiley-Blackwell, 2004)
This work presents a two-dimensional (2-D) study of the modal spectrum of a single microstrip and a pair of coupled microstrip lines with an upper dielectric half-space. This 2-D study is postulated as the necessary step ...

A suitable integral equation for the quasi-TEM analysis of hybrid strip/slot-like structures
(Institute of Electrical and Electronics Engineers, 2001)
This paper reports on a suitable formulation of the spectraldomain/integral-equation method for the quasi-TEM analysis of hybrid strip/slot-like planar lines. The free surface charge distribution is used as an unknown on ...

Comparative Analysis of Edge- and Broadside-Coupled Split Ring Resonators for Metamaterial Design - Theory and Experiments
(Institute of Electrical and Electronics Engineers, 2003)
This paper develops a quasi-analytical and self-consistent model to compute the polarizabilities of split ring resonators (SRRs). An experimental setup is also proposed for measuring the magnetic polarizability of these ...

Evaluation of the radar cross section of circular microstrip patches on anisotropic and chiral substrates
(Institute of Electrical and Electronics Engineers, 2001)
Galerkin's method in the Hankel transform domain (HTD) is applied to the determination of the radar cross section (RCS) of a circular microstrip patch printed on a substrate which may be an uniaxial anisotropic dielectric, ...

Design of wide-band semi-lumped bandpass filters using open split ring resonators
(Institute of Electrical and Electronics Engineers, 2007)
Open split ring resonators (OSRRs) are used in this letter to design wide-band semi-lumped bandpass filters. OSRRs work as lumped LC series elements due to their small electrical size and can be then used as building blocks ...

Dual capacitive-inductive nature of periodic graphene patches: Transmission characteristics at low-terahertz frequencies
(American Physical Society, 2013)
We report on the dual nature (capacitive and inductive) of the surface impedance of periodic graphene patches at low-terahertz frequencies. The transmission spectra of a graphene-dielectric stack shows that patterned ...

Design of Broadband Aperture-Coupled Stacked Microstrip Antennas Using Second-Order Filter Theory
(IEEE, 2022-07)
In this article, the authors propose a lumped circuit methodology for the design of broadband stacked microstrip patch antennas fed through an aperture. First, an equivalent circuit (EC) is introduced for the antenna. The ...
