Existing position-based unicast routing algorithms which forward packets in the geographic direction of the destination require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is ...

We develop channel estimation techniques for multiple-input multiple-output (MIMO) channels that employ space-time block-coded (STBC) transmissions. We derive the MMSE channel estimator for multi-user Alamouti STBC transmissions over both flat fading and f ...
We show that network coding allows to realize significant energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus ...
We experimentally measure and theoretically model the light transmission characteristics of subwavelength apertures. The characterization consists of translating a point source at varying vertical height and lateral displacement from the aperture and measu ...
This paper investigates a cable transmission to remotely actuate MR compatible robots over a distance of several meters. Such a transmission could be an interesting solution for haptic interfaces for neuroscience studies performing force feedback during fu ...
Polymers have the ability to conform to surface contours down to a few nanometres. We studied the filling of transparent epoxy-type EPON SU-8 into nanoscale apertures made in a thin metal film as a new method for polymer/metal near-field optical structures ...
This paper investigates the use of embedded optical fiber Bragg gratings to measure strain near a stress concentration within a solid structure. Due to the nature of a stress concentration (i.e. the strong non-uniformity of the strain field) the assumption ...
Several approaches are described with the aim of producing near-field optical probes with improved properties. Focused ion beam milling allows the fabrication of small apertures in a controlled fashion, resulting in probes with excellent polarization prope ...
