Coupling between common mode ESD and transmission lines inside shielded enclosures

A lot of well documented operation anomalies, but also many catastrophic failures on board of orbiting spacecraft are due to electrostatic discharge (ESD). Therefore an accurate design is necessary to protect the circuitry from the effects of a broad band disturbing field due to an ESD, but this can be achieved when effective simulation tools are available. In this sense, this paper presents a model for the evaluation of the disturbance induced in a transmission line by a common mode ESD occurring inside a metallic enclosure, representing the metallic shield of an apparatus. Theoretical results are validated by measurements.
