Microscopic theory of refractive index applied to metamaterials: Effective current response tensor corresponding to standard relation $n^2 = \varepsilon_{\mathrm{eff}} \mu_{\mathrm{eff}}$

open access: yes, 2018
In this article, we first derive the wavevector- and frequency-dependent, microscopic current response tensor which corresponds to the "macroscopic" ansatz $\vec D = \varepsilon_0 \varepsilon_{\mathrm{eff}} \vec E$ and $\vec B = \mu_0 \mu_{\mathrm{eff}} \

A universal platform for magnetostriction measurements in thin films

open access: yes, 2015
We present a universal nanomechanical sensing platform for the investigation of magnetostriction in thin films. It is based on a doubly-clamped silicon nitride nanobeam resonator covered with a thin magnetostrictive film.

Optical constants of Cu ZnSnS bulk crystals

open access: yesMoldavian Journal of the Physical Sciences, 2009
The dielectric functions of Cu2ZnSnS4 bulk crystals grown by the Bridgman method were measured over the energy range 0.8 to 4.7 eV at room temperature using variable angle spectroscopic ellipsometry. The spectral dependence of complex refractive index,

Solitons in spiraling Vogel lattices

open access: yes, 2012
We address light propagation in Vogel optical lattices and show that such lattices support a variety of stable soliton solutions in both self-focusing and self-defocusing media, whose propagation constants belong to domains resembling gaps in the ...
