What is the Electromagnetics and Space Environment domain?
Electromagnetics and Space Environment encompasses two technical fields: one concerned with issues of electromagnetic transmission, reception, propagation and interaction, and another looking at the troublesome effects of the orbital environment. On the “desired effects” side the main topics are antenna design and study of the propagation of electromagnetic waves, in particular through the atmosphere and in other complex environments (e.g. how the signal coming from a satellite propagates in a city with tall buildings and within them). All spacecraft require electromagnetic compatibility (EMC) between their various equipment and subsystems, which demands a dedicated test campaign. Antennas are the single most sensitive satellite element to interference, because they operate by deliberately turning electromagnetic fields into electric currents and vice versa. The work includes modelling and testing how spacecraft designs might affect antenna performance, taking account of adjacent elect
