This thesis work aims to optimize the treatment of hydrocephalus. It consists of two distinct objectives: the optimization of the diagnosis of patients implanted with a shunt system for the derivation of cerebro-spinal fluid (CSF) and the optimization of t ...
Thanks to its physical characteristics, Ultra-wideband (UWB) is one of the most promising technologies for indoor pedestrian navigation. UWB radio localisation systems however experience multipath phenomena that decrease the precision and the reliability o ...
Different decoupling sequences are tested - using various shaped radio-frequency (RF) pulses - to achieve the longest possible lifetimes of singlet-state populations over the widest possible bandwidths, that is, ranges of offsets and relative chemical shif ...
700nm parametric conversion in silica fiber from near-infrared to short-wave infrared band is reported for the first time. The conversion efficiency in excess of 40dB was measured between 1300nm signal and 2000nm idler band. ...
Spin-wave modes in Ni80Fe20 thin-film antidot lattices are investigated using micromagnetic simulations and a semianalytical theoretical approach. The simulations reveal a rich eigenmode spectrum consisting of edge and center modes. We find both spatially ...
We investigate a measurement technique based on High Resolution Interference Microscopy (HRIM). HRIM allows the characterization of amplitude and phase of electromagnetic wave-fields in the far-field with a spatial accuracy that corresponds to a few nanome ...
Broadband spectroscopy on spin waves is performed on a square Ni 80 Fe 20 antidot lattice with deep-submicron holes. Depending on the in-plane magnetic field H applied under different angles η , characteristic multiple resonances are resolved. Substantiate ...
A record 730 nm parametric conversion in silica fiber from the near-infrared to the short-wave infrared band is reported and analyzed. A parametric gain in excess of 30 dB was measured for a signal at 1300 nm (with corresponding idler at 2030 nm). This con ...
The spatial distribution of surface electromagnetic waves on a one-dimensional photonic crystal with a polymeric grating on top is mapped using a multiheterodyne scanning near-field optical microscope. The grating opens a bandgap. At the band edges, a stat ...
New results on electron heat wave propagation using ion cyclotron resonance heating power modulation in the Joint European Torus (JET) [P. H. Rebut , Nucl. Fusion 25, 1011 (1985)] plasmas characterized by internal transport barriers (ITBs) are presented. T ...
