Modeling the electrophoretic deposition of colloidal particles
(IOP Publishing Ltd., 2001)
This letter presents the results of numerical simulations of the buildup of a layer of colloidal particles on an electrode. In a low-frequency electric field, particles suspended in a low-conductivity liquid migrate to one ...

Magnetic field induced inversion in the effect of particle size on powder cohesiveness
(AIP Publishing, 2010-07)
Experimental measurements are reported on the tensile yield stress of magnetofluidized beds of fine magnetic powders operated in the cross-flow configuration. In the absence of externally applied magnetic field the yield ...

Dynamics of EHD Laminar Plumes: scaling analysis and integral model
(AIP Publishing, 2000)
In this paper electrohydrodynamic (EHD) plumes are examined in the region far from the injecting electrode and the collector plate, for both two-dimensional and axisymmetric geometries. The relative importance of the ...

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 ...

Mesoscopic structuring and yield stress of magnetofluidized fine particles
(IOP Publishing Ltd., 2009-10)
The fluidization behavior of a bed of fine magnetizable particles excited by an externally applied magnetic field is found to depend on the aggregative nature of the particles before the field was applied. Usually nonaggregated ...

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 ...
