Investigation of Charged Particles Radiation Moving in a Homogeneous Dispersive Medium
(Materials & Energy Research Center-Merc, 2017)
In this work, we use Drude-Lorents model description to study the radiation of a charged particles moving in a homogeneous dispersive medium. A suitable quantized electromagnetic field for such medium is utilized to obtain ...
Classification of dispersion equations for homogeneous, dielectric-magnetic, uniaxial materials
(Optical Society of America, 2006-12)
The geometric representation at a fixed frequency of the wave vector (or dispersion) surface ω(k) for lossless, homogeneous, dielectric-magnetic uniaxial materials is explored for the case when the elements of the relative ...
Uniaxial dielectric media with hyperbolic dispersion relations
(John Wiley & Sons Inc, 2006-02)
Planewave propagation with hyperbolic/hyperboliclike characteristics in uniaxial dielectric media is investigated. The phase velocity is positive with respect to the time-averaged Poynting vector for both evanescent and ...
Classical homogenization to analyse the dispersion relations of spoof plasmons with geometrical and compositional effects
(Royal Society Publishing, 2015)
We show that the classical homogenization is able
to describe the dispersion relation of spoof plasmons
in structured thick interfaces with periodic unit cell
being at the subwavelength scale. This is because the
interface ...
Explicit estimates versus numerical bounds for the electrical conductivity of dispersions with dissimilar particle shape and distribution
(Springer, 2020-08-01)
An effective-medium theory for the electrical conductivity of Ohmic dispersions taking explicit account of particle shape and spatial distribution independently is available from the work of Ponte Castañeda and Willis [J ...
Desing and model of piezoelectromagnetic metamaterials
(Benemérita Universidad Autónoma de Puebla, 2017-09)
"This dissertation introduces a novel theory of piezoelectromagnetic crystal homogenization which provides the basis to characterize media with nonlocal piezoelectric and piezomagnetic properties, normally described by ...
Protected magnetic particles: Silica on yttrium iron garnet
(2001-12-01)
The formation of silica on core yttrium iron garnet presents a variety of different applications as corrosion resistance and stabilization of magnetic properties. Well-defined magnetic particles were prepared by heterocoagulating ...
