Guided modes in left-handed waveguides
(OPTICS COMMUNICATIONS, 2008)
We investigate basic properties of linear guided modes in a waveguide slab with the core of a material with simultaneously negative effective permittivity and permeability surrounded by a normal dielectric cladding. The ...

Cerium Oxide Based Nanometric Powders: Synthesis and Characterization
(Science of Sintering, 2007)
Nanometric powders of solid solutions of cerium oxide were obtained by a modified
glycine nitrate procedure. Solid solutions of the host compound CeO2 with one or more
dopants in the lattice were synthesized. Rare earth ...
