Planar magnetoinductive wave transducers: Theory and applications
(American Institute of Physics, 2004)
Transduction of raagnetoinductive waves (MIWs) in planar technology is demonstrated. A transducer consisting of a one-dimensional periodic array of metallic split squared ring resonators (SSRR), placed between a pair of ...

Granular avalanches: Deterministic, correlated and decorrelated dynamics
(IOP Publishing Ltd., 2004-12-15)
A statistical analysis of granular avalanches in a half-filled and slowly rotated drum is presented. For large-sized grains the classical coherent oscillation is reproduced, i.e. we observe a quasi-periodic succession of ...

Parallel coupled microstrip filters with ground-plane aperture for spurious band suppression and enhanced coupling
(Institute of Electrical and Electronics Engineers, 2004)
Parallel coupled microstrip sections with a slotted ground plane are proposed as building blocks of coupled-line microstrip filters with enhanced performance. It is shown that, by proper adjustment of the ground-plane slot ...

Jamming Threshold of Dry Fine Powders
(American Physical Society, 2004)
We report a novel experimental study on the jamming transition of dry fine powders with controlled attractive energy and particle size. Like in attractive colloids dry fine particles experience diffusionlimited clustering ...

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. ...

The Sevilla Powder Tester: A Tool for Characterizing the Physical Properties of Fine Cohesive Powders at Very Small Consolidations
(Hosokawa Powder Technology Foundation, 2004)
We present a fluidized bed apparatus that enables us to test the bulk mechanical properties such as the yield stresses and compressibility of fine cohesive powders. Every measurement is preceded by driving the powder ...

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 ...

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 ...
