Coronal Mass Ejections (CMEs) are related to the formation of large-scale magnetized plasma disturbances traveling through the corona and the solar wind which can have a significant impact on Earth. Along their path CMEs drive fast mode shocks, which in turn accelerate ions and electrons. The accelerated electrons can generate type II radio bursts and serve as an indicator of shocks near the Sun....
The solar wind is a supersonic and super-Alfvenic plasma flow of solar origin filling the whole heliosphere. It has a strong turbulent character with several energy cascades. Interplanetary (IP) shocks are characterized by abrupt changes of plasma parameters and the magnetic field strength. Primary drivers of IP shocks are transient phenomena such as coronal mass ejections and corotating interaction...
The transport of energy in space plasmas, especially in the solar wind, is far from being understood. Electrons are expected to play a major role for energy transport. Therefore, measuring accurately the temperature of the electrons and their non-thermal properties is essential to understand the transport properties of plasmas in non-local thermodynamic equilibrium. Quasi-thermal noise spectroscopy...
In a complex product development environment designers and engineers demand simple but technically relevant methods to visualize knowledge. To address this issue, Lean Product and Process Development (LeanPPD) project, funded by the European Commission (NMP-2008–214090), development a new paradigm based on lean thinking, providing a knowledge-based environment to support engineering decision taking...
We considered theoretically and experimentally one-dimensional multilayered metallodielectric nanofilms with nanometric thickness for imaging below the diffraction limit. We investigated their behavior in the ultraviolet and visible spectrum from the point of view of near field optics, but also considered some of their properties in the far field. We designed our structures using the transfer matrix...
We analyzed the use of subwavelength ordered nanohole patterns for detection of miniscule amounts of biological analytes. Owing to their surface plasmon resonance (SPR) operation, such structures show an extraordinarily high optical transmission in visible spectrum, at the same time concentrating the illumination to the very small area of the nanoholes and being much more sensitive to refractive index...
