Description
The Applied Electromagnetism Group (GEA) has more than twenty years’ experience in developing software tools for the analysis and design of passive devices, periodical structures and antennas for space applications. The group has implemented efficient numerical methods in computational electromagnetics, such as MoM, FEM, Modal Analysis and Domain Decomposition. Different waveguide components (polarizers, filters, diplexers/triplexers, OMTs, power-combiners, Beam-Forming-Networks) and dichroic sub-reflectors have been designed, built and tested. Some of them have flight in Telecom satellites (Hispasat-1A-B-C-E, Artemis, Sesat, Astra-1K-3B-1M, Europe*Star, Newbird, Sky-Bridge, Eutelsat-W2A, Amazonas-2-5, among others) and scientific missions (Mars Express, Venus Express, Rosetta, Herschel-Planck, Bepi-Colombo).
