How is this new?
This has potentially been a problem for years with radar and comms gear being vulnerable to nuclear generated EMP.
The only difference with the 'pulse bomb' would be that the power would be much lower, and probably not spread over such a range of frequencies.
One assumes that existing countermeasures (technical or *cough* having some spare bits ready on the shelf *cough*) will still be adequate to deal with any new threats.
Of course civil equipment is less likely to be in a position to deal with this than military, though I guess that civil stuff would be covered by a similar design philosophy to that used in at least some military hardware: the scenario is extremely unlikely to happen, and if it does there would be other effects anyway, so it's not even worth bothering to introduce countermeasures.
