The use of sensors has grown dramatically in recent years and many devices rely on the information they provide. The lack of proper security mechanisms available to control the use of sensors and the high degree of integration make them more vulnerab

Recent technological developments considerably lowered the barrier for unmanned aerial systems (UAS) to be employed in a variety of usage scenarios, comprising live video transmission from otherwise inaccessible vantage points. As an example, in the

This paper describes an experimental study of gamma radiation effects in low-density arrays of vertically aligned carbon nanotubes. These arrays are characterized by excellent anti-reflective and absorbing properties for wavelengths from UV to IR, wh

Weak localization is investigated for a two-dimensional electron gas subject to a cosine-potential in one direction. With decreasing Fermi energy the system gradually develops into an array of almost isolated quantum wires of finite width. Interferen

The European Space Agency (ESA) in the frame of its General Study Program (GSP) has started to investigate the opportunity of using metamaterials in space applications. In that context, ESA has initiated two GSP activities which main objectives are 1

Weak-localization negative magnetoresistance is calculated for semiconductor quantum wires with use of the nonequilibrium-Green-function technique. Because of the low electron densities the localization length can become comparable with the phase-coh

The conductance of a ballistic quantum wire between two reservoirs exhibits steps of height 2e 2 /h, if the occupation of transverse subbands is changed. We investigate conditions for observation of these steps starting from Kubo-Greenwood formula. W
