EMP generation near objects with cylindrical symmetry in the source region

It has long been recognized that the electromagnetic (EM) source terms in the region close to a nuclear explosion consist of Compton and photoelectric currents and collision-induced conductivity [1]. These source terms create a pulse of EM field (EMP) both in the region itself and outside the source region [2]. For an object outside the source region, the EMP effect is produced through free-field coupling [3]. For an object inside the region, the EMP effect should be obtained by solving the boundary value problem using the current and the conductivity directly as the driving source.
