Strong spatial dispersion in wire media in the very large wavelength limit
(American Physical Society, 2003)
It is found that there exist composite media that exhibit strong spatial dispersion even in the very large wavelength limit. This follows from the study of lattices of ideally conducting parallel thin wires (wire media). ...

Split ring resonator-based left-handed coplanar waveguide
(American Institute of Physics, 2003)
Left-handed wave propagation in a CPW, coupled to split ring resonators and periodically loaded with signal-to-ground wires acting as inductors, was demonstrated. Since negative permeability and permittivity coexist only ...

Full-wave analysis of the excitation of magnetostatic-surface waves by a semi-infinite microstrip transducer - Theory and experiment
(Institute of Electrical and Electronics Engineers, 2003)
This paper presents a new method for the complete characterization of the radiation of magnetostatic-surface waves in microstrip transmission lines with longitudinal magnetization. This method is based on the analysis of ...

Insertion loss of magnetostatic-surface wave transducers - Transmission-line model and experiment
(Institute of Electrical and Electronics Engineers, 2003)
In this paper, a transmission-line model is developed for the computation of the insertion loss of magnetostatic-surface wave transducers and measurements are carried out by the authors to check this model. In a first step ...

Babinet principle applied to the design of metasurfaces and metamaterials
(American Physical Society, 2004-11-05)
The electromagnetic theory of diffraction and the Babinet principle are applied to the design of artificial metasurfaces and metamaterials. A new particle, the complementary split rings resonator, is proposed for the design ...

Enhanced backward wave propagation in evanescent waveguides loaded with split ring resonators
(AIP Publishing, 2007)
This paper reports on the design and experimental characterization of evanescent waveguides loaded with split ring resonators SRRs supporting enhanced backward wave propagation. With respect to previous negative refractive ...

Correct denition of the Poynting vector in electrically and magnetically polarizable medium reveals that negative refraction is impossible: comment
(Optical Society of America, 2009)
It is shown that, when all macroscopic currents associated with the electric and magnetic polarizability are properly accounted for, the standard expression for the Poynting vector and the average work exerted by the ...

Comments on "Internal impedance of conductors of rectangular cross section"
(Institute of Electrical and Electronics Engineers, 2001)
The alternate current (ac) internal impedance of rectangular cross-sectional conductors used as transmission lines and interconnects in microwave and digital printed circuits were analyzed. The difference between the real ...

Artificial magnetic metamaterial design by using spiral resonators
(American Physical Society, 2004)
A metallic planar particle, that will be called spiral resonator (SR), is introduced as a useful artificial atom for artificial magnetic media design and fabrication. A simple theoretical model which provides the most ...

Accurate modeling of split ring metamaterial lenses for magnetic resonance imaging applications
(AIP Publishing, 2009)
The usefulness of thin split ring metamaterial slabs for imaging applications, including magnetic resonance imaging applications, has attracted some attention in the past years. However, the small number of unit cells ...
