We investigate bi-component magnonic crystals consisting of periodic square lattices of Co nanodiscs embedded in Permalloy thin films. Micromagnetic simulations are used to analyse experimental data obtained with both all-electrical broadband spectroscopy ...

Dynamic control of light transmission through multimode fibers

Ioannis Papadopoulos

In the present thesis we demonstrate how under the appropriate dynamic control of light propagation, multimode fibers can be transformed into deterministic optical elements that along with their ultrathin size, large number of degrees of freedom and high N ...

Developing luminescent Brownian probes for near-field investigations of the intracellular environment

Flavio Maurizio Mor

Life sciences have a constantly growing need for novel methodological approaches suitable to investigate the intracellular environment with increased temporal and spatial resolutions. Recently, optical near-field probes, such as laser-irradiated pointed me ...

Contrast Enhancement in Optical Coherence Microscopy

Christophe Pache

Optical Coherence Microscopy (OCM) is a three-dimensional imaging technique that provides cross-sectional views of the subsurface microstructure of biological tissue, with a high axial and lateral resolution. In OCM, a low time coherence light source is sp ...

Interest in high resolution imaging techniques has recently multiplied due to their importance in bio-medical research. Quantitative phase measurements by holographic microscopy is an extraordinary tool to gain new understanding of transparent biological s ...

We study nontrivial applications of the reduced basis method (RBM) for electromagnetic applications with an emphasis on scattering and the estimation of radar cross section (RCS). The method and several extensions are explained with two examples with diffe ...

We present a comparison between sum frequency scattering (SFS) and reflection mode sum frequency generation (R-SFG). We have used scattering theory to describe both scattering experiments as well as reflection mode experiments. The interfacial vibrational ...

The Investigation of highly confined light fields created by different mechanisms, such as refraction, diffraction, and scattering, are the main subject of this thesis. We distinguish a specific scattering phenomenon of dielectric microspheres from general ...

We present a theoretical framework for the generation and scattering of second-harmonic and sum-frequency light from the surface of particles of arbitrary shape in the limit of low index of refraction contrast. For homogeneous and isotropic surfaces, light ...

We simulate apertureless near-field optical imaging and obtain phase and amplitude scans of structured substrates for elastic scattering. The solution of the three-dimensional Maxwell equations does not involve approximations and we include large tips and ...
