HIRF SE (High Intensity Radiated Fields Synthetic Environment) is a computational tool for the simulation and analysis of electromagnetic field interaction with aircraft and rotorcraft in HIRF radio frequency range (10 kHz-40 GHz). The tool allows the simulation of air vehicle interaction with both far-field and near-field sources having any polarization and position in the presence or not of the ground, and it will be applied during design and certification phases in order to cope with the increasing complexity of air vehicles electronic/electric architectures and of the electromagnetic environment. The research leading to these results has received funding from the European Community's Seventh Framework Programme [FP7/2007-2013] under grant agreement no. 205294. © 2012 IEEE.

We describe CLAC (Conservation Laws Approximation on many Cores), a generic Discontinuous Galerkin (DG) solver for three-dimensional electromagnetic simulations. The solver runs on clusters of GPUs, it is based on hybrid parallelism using the OpenCL and MPI libraries. We explain how to solve the Vlasov-Maxwell equations with this tool. We present several numerical results.

The purpose of this paper is to present a high fidelity simulation tool named "EMCASL" able to predict the disturbances conducted on the power bus of a spacecraft, and more generally, of any complex system. This advanced simulation tool handles the 'conducted noise' electromagnetic compatibility among the various units and subsystems of the satellite and enables engineers to evaluate the effects of EMI on flight system, so that potential EMC problems can then be identified and solved in a timely manner. The system noise model is based on time and frequency domain equipment measurement in both differential and common mode and on appropriate behavioural modelling of any power conditioning and distribution units. The tool has been developed by Astrium Satellites and AxesSim in the frame of an ESA contract 22990/09/NL/GLC. © 2012 ESA.

A simple method permitting to obtain a homogeneous panel from a strongly inhomogeneous panel is presented. The method consists of determining the characteristics of a panel having an equivalent conductivity obtained from a near-field magnetic shielding effectiveness measurement. Thus, the method suitable for frequencies lower than 1MHz does not require the knowledge of the detailed internal geometry of the sample. After the validation of the measurement setup on a copper plate of known conductivity, two space composite panels are characterized and homogenized. © 2012 IEEE.

Improvements of a methodology [1] able to compute the parasitic electromagnetic emissions of a solar panel are presented in this paper in order to handle real solar panels. Thus, the method is able to take into account solar panels with triple-junction solar cells, series or shunt power regulation system, and honeycomb composite panels. This numerical method is validated experimentally by comparing the near magnetic field emitted by a real solar panel and calculated by the method. © 2014 IEEE.
