Recent Developments and Challenges for Reflector Antenna EM-Modelling

This paper concerns the EM-modelling of high-accuracy reflector antenna systems, and in particular of reflectors for space antenna systems. Recent modelling developments are exemplified ranging from general software enhancements to meet customer needs, over specific developments on a particular demanding project, to new research projects. In addition, challenges for the next generation of reflector antenna EM-modelling tools are addressed.
