Modern electronic systems are susceptible to intense electromagnetic fields. Due to the small feature size and the low supply voltage of the electronics, the currents and voltages induced in signal and power lines cause malfunction of electronic circuits and components. During decades high power electromagnetic sources have been developed providing electromagnetic fields in the order of several hundreds of Mega Watts up to the Giga Watts level. For electronic components and smaller electronic systems, protection against the powerful electromagnetic radiation may be realized on a component or on a sub-system level. However, for larger electronic systems or electronic based infrastructures like communication centres, control centres or power plants, provision of a protected “hotel room atmosphere” and therefore shielding of the room or building itself may be mandatory.
A new time domain measurement technique has been developed, which allows to measure shielding efficiencies already during the construction phase of a building in order to ensure proper shield installation.
High power electromagnetic pulses may also being used to defeat against modern electronic weapon systems and other electronic threats. Various HPEM sources have been developed emitting high power electromagnetic radiation in a single pulse or a burst of pulses targeting the control and computer electronics of modern electronic systems and infra structures. Those sources are able to disrupt the control units of engines and may be used to stop cars, to control admission to sensible or high value areas or to stop speed boats or jet-skis in order to control access to harbours and moored ships from sea side.
