Forgive me my ignorance, but if a faraday cage is a metal box, is my vehicles trunk adequate or do I need to research the matter more thoroughly? I ask this question for the benefit of others as well as my own stupid self
The Vehicle trunk will make for a Faraday cage but a electronic leaky one for the higher speed pulse effects such as intense X-ray induced Crompton electron cascade from a High altitude nuclear EMP (HEMP). It will be perfectly OK for the natural EMP such as SME's interaction with the earths magnetosphere and geomagnetic effects, which changes the impedance from the Power station Source to the distributed loads to induce high currents in long line transmission lines.
