Description
The activity has been devoted to the development of a proof-of-concept demonstrator of a parametric electromagnetic modelling system for antenna design, antenna interactions and related radiated electromagnetic compatibility problems, based on the combination of simple-fast and accurate-slow models. The system is able to start the simulation process using existing detailed CAD models of the satellite layout and has the capability to perform parametric computations on the resulting RF-models. It includes three interweaved elements:
• Semi-automated CAD model simplification and extension with electromagnetic data also handling parameterised geometries.
• Parameterisation of modelling algorithms and problem partitioning, making very large problems affordable without compromising accuracy.
• Physics-based parametric techniques, making complex computational procedures fast and accurate.
The system kernel is programmable to allow user defined procedures, which can in turn be combined into more and more complex computational processes. The electromagnetic modelling and data processing and visualisation capabilities can be extended by adding new basic modules to the system library, via a simple wrapping mechanism.
Demonstration tests have shown the applicability of the system to realistic CAD files of the complete platform as well as the effectiveness and efficiency of the whole computational core, in particular of the parametric techniques.
