Light scattering by magnetoelectrically gyrotropic sphere with unit relative permittivity and relative permeability [PDF]
Journal of the Optical Society of America A, 2014 An exact transition matrix was formulated for electromagnetic scattering by a sphere made of a magnetoelectrically gyrotropic material with unit relative permittivity and relative permeability. The total scattering and forward scattering efficiencies are lower when the magnetoelectric gyrotropy vector of the sphere is either coparallel or antiparallel ...

Size-Dependent Bruggeman Approach for Dielectric-Magnetic Composite Materials
, 2004 Expressions arising from the Bruggeman approach for the homogenization of dielectric-magnetic composite materials, without ignoring the sizes of the spherical particles, are presented. These expressions exhibit the proper limit behavior.

Dielectric properties of CaCu3Ti4O12 based multiphased ceramics [PDF]
, 2006 A “soft chemistry” method, the coprecipitation, has been used to synthesize the perovskite CaCu3Ti4O12 (CCT). Three main types of materials were obtained for both powders and sintered ceramics: a monophased consisting of the pure CCT phase, a biphased ...

Advanced Engineering Materials, EarlyView.Highly textured CeO2 nanowires and nanoporous thin films are successfully synthesized by water dissolution of Sr3Al2O6 (SAO) from the SAO:CeO2 vertically aligned nanocomposites (VANs). The morphology of CeO2 can be varied by VAN composition. It demonstrates a new method for synthesizing nanostructured CeO2 without chemical etching or complex micro ...

Modeling columnar thin films as platforms for surface-plasmonic-polaritonic optical sensing
, 2009 Via exploitation of surface plasmon polaritons (SPPs), columnar thin films (CTFs) are attractive potential platforms for optical sensing as their relative permittivity dyadic and porosity can be tailored to order. Nanoscale model parameters of a CTF were
