Micro- and nanoflowers are a class of materials composed of particles with high surface-to-volume ratio. They have been extensively studied in the last decade due to simple preparation protocols and promising applications in biosensing, as drug deliv

Using RF magnetron sputtering, we deposited Bi12TiO20 (BTO) thin films on various substrates (glass, quartz, stainless steel (SS304), (001) and (111) Si and sital-ceramics, Al and Cu foils). The films had a constant thickness of 1.3 μm. The as-depos

The propagation length of surface plasmon polaritons (SPP) is limited by the internal losses in the metal and the radiation losses due to the structure imperfections at the interface. These losses can be compensated by introducing material with optic

Surface plasmons could allow the fabrication of optical devices operating below the diffraction limit. This requires optical coupling of the plasmonic components and other optical systems. A good carrier for surface plasmon waves are metal nanowires.

Surface plasmons propagate with losses due to internal absorption of energy in the metal. Here we investigate an infinite metal cylindrical waveguide embedded in dielectric medium. If the dielectric is replaced with an active gain medium it is possib

We give an unambiguous analytical solution of the inverse problem of multiple ellipsometric data, taken at different (arbitrary and preliminary unknown) thicknesses of an embedded nonabsorbing uniform layer. The solution uses all available data in th
