—Particle-based simulations running on large high-performance computing systems over many time steps can generate an enormous amount of particle-and field-based data for post-processing and analysis. Achieving high-performance I/O for this data, effectively managing it on disk, and interfacing it with analysis and visualization tools can be challenging,(More)
This article presents the RF characterization results of a large-area MCM-D technology developed within the EU LAP project. Microstrip lines were simulated, designed, and manufactured in several material combinations. Measurements up to 120 GHz showed good coincidence between simulation and reality. Future work is dedicated to filters and antennas in the 77(More)
Significant problems facing all experimental and computational sciences arise from growing data size and complexity. Common to all these problems is the need to perform efficient data I/O on diverse computer architectures. In our scientific application, the largest parallel particle simulations generate vast quantities of six-dimensional data. Such a(More)
Two dedicated RF test vehicles (RF-TV) have been designed to characterise the high frequency performance of a new low-cost thin film (MCM-D) technology, fabricated on large area panels (LAP). Previous investigations revealed the capabilities of the new LAP technology to be used at frequencies up to 110 GHz. Test structures for transmission measurements,(More)
We present a numerical model for time domain re-flectometry (TDR) signal propagation in dispersive dielectric materials. The numerical probe model is terminated with a parallel circuit, consisting of an ohmic resistor and an ideal capacitance. We derive analytical approximations for the ca-pacitance, the inductance and the conductance of three-wire probes.(More)
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract We present a numerical model for time domain reflectometry (TDR) signal propagation in dispersive dielectric materials. The numerical probe model is terminated with a parallel circuit, consisting of an(More)
The significant increase in planned offshore wind parks and the tendency towards large parks in considerable distances offshore, make the well established HVDC technology a favorable solution for the connection of these large & distant offshore wind parks to the main power grid onshore. It is therefore necessary to adequately model the HVDC transmission(More)
We introduce the dune-curvilineargrid module. The module provides the self-contained, parallel grid manager, as well as the underlying elementary curvilinear geometry module dune-curvilineargeometry. This work is motivated by the need for reliable and scalable electromagnetic design of nanooptical devices. Curvilinear geometries improve both the accuracy of(More)
