Towards a systematic design of isotropic bulk magnetic metamaterials using the cubic point groups of symmetry
(American Physical Society, 2007)
In this paper, a systematic approach to the design of bulk isotropic magnetic metamaterials is presented. The roles of the symmetries of both the constitutive element and the lattice are analyzed. For this purpose, it is ...

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 ...

Near-field imaging in the megahertz range by strongly coupled magnetoinductive surfaces: Experiment and ab initio analysis
(AIP Publishing, 2006)
In this work, the previously reported near-field imaging by two strongly coupled arrays of planar magnetic resonators is further studied. Experiments are performed to clarify the physical mechanisms underlying such an ...

Analytical theory of extraordinary transmission through metallic diffraction screens perforated by small holes
(Optical Society of America, 2009)
In this letter, the problem of extraordinary (ET) transmission of electromagnetic waves through opaque screens perforated with subwave- length holes is addressed from an analytical point of view. Our purpose was to find a ...

High viscosity gas fluidization of fine particles: An extended window of quasihomogeneous flow
(American Physical Society, 2006)
We explore the role of gas viscosity in the behavior of gas-fluidized beds of fine powders by means of experimental measurements using nitrogen and neon as fluidizing gases, and theoretical considerations. The existence ...
