Localisation of buried ferromagnetic objects based on minimum-norm-estimations A simulation study

Purpose – The purpose of this paper is to examine the localisation of ferromagnetic objects buried in the underground. More specifically, it deals with the reconstruction of the XY-positions, the depths...

Internal magnetic fields in submicron particles of barium hexaferrite detected by Fe-57 NMR

All Fiber Mach-Zehnder Interferometer Based on Suspended Twin-Core Fiber

Response of FBGs in Microstructured and Bow Tie Fibers Embedded in Laminated Composite

Fiber Bragg gratings in bow tie fiber and highly birefringent microstructured optical fiber are embedded in a carbon fiber reinforced epoxy. The Bragg peak wavelength shifts of the embedded gratings are...

Structured-Core GeO2-Doped Photonic-Crystal Fibers for Parametric and Supercontinuum Generation

Fabry-Perot Cavity Based on a Suspended-Core Fiber for Strain and Temperature Measurement

A fiber-optic Fabry–Pérot sensing structure based on the utilization of a suspended-core fiber is presented. The interferometric structure is formed when a small length of the suspendedcore fiber is...

Selectively Deposited Silver Coatings on Gold-Capped Silicon Nanowires for Surface-Enhanced Raman Spectroscopy

Gold caps on silicon nanowires are hemispherical and only a few tens of nanometers in diameter when grown from metal catalysts by the vapor-liquid-solid growth mechanism using chemical vapor deposition....

Reconstruction of high-resolution holographic microscopic images

In in-line holographic microscopy a pinhole illuminates an object and a CCD-detector directly records the hologram in a pixel-pitch-dependent distance. A rapidly calculating exact reconstruction technique...

Impact of fixation on in vitro cell culture lines monitored with Raman spectroscopy

Raman spectroscopy provides chemical-rich information about the composition of analytes and is a powerful tool for biological studies. With the ability to investigate specific cellular components or image...

Negative-index materials: Two approaches for nanofabricated metamaterials

In this work we present results on the practical realization of optical negative-index metamaterials based on two different geometries for the visible and near infrared (NIR) domains. A detailed description...
