Lightning responses on a finite cylindrical enclosure

Lightning coupling to the enclosure interior can occur in three distinct ways: (1) lightning can attach to the enclosure and the resulting lightning current flowing in the enclosure wall can cause voltage inside the enclosure wall (an attachment); (2) lightning can strike a conductor close to the enclosure (but not the enclosure) and the resulting magnetic flux can induce a voltage inside the enclosure (the distance from the line source to the enclosure can vary theoretically from 0 (closest induction coupling) to some distance (close coupling)); (3) lightning can strike further away from the enclosure (uniform field-drive induction).
