The preparation of responsive multilayered structures with quarter-wave design based on layer-by-layer deposition of sol-gel derived Nb(2)O(5) films and spin-coated MEL type zeolite is demonstrated. The refractive indices (n) and thicknesses (d) of the layers are determined using non-linear curve fitting of the measured reflectance spectra. Besides, the surface and cross-sectional features of t...

X-ray diffraction measurements were performed on Co?Pt1-?/Pd, Co/Pd, Co/Fe, and Co/W multilayer samples with different structures, such as Co?Pt1-? alloy layer composition ?, bilayer thickness, and number of bilayers. Multilayer samples were made by magnetron sputtering in a chamber with multi-parallel guns and a position controllable substrate. Co?Pt1-? alloy layers were deposited by cosputter...

A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite bounding media where each layer may have a frequency dependent dielectric function and ...

Applying the concept of spectral domain representation, the moment method or the point-matching procedure and Green's function theory, a unified approach for the computation of the static capacitance of single, coupled and comb-like metallic structures in anisotropic multilayered media is presented. The media can be electrically shielded on one or both sides. The geometry of the parallel strips...

 In this work electrodeposited Ni-Cu/Cu metallic multilayered films with different thicknesses of Ni and Cu were prepared on (100) polycrystalline Cu substrates. The nanostructure of the multilayers was studied using XRD. The existence of satellite peaks in the XRD patterns showed that the multilayered films have superlattice structures. The difference between the intensity of ML(200) and ML(11...
