Gy. Wen et al., ELECTROMAGNETIC MISSILES GENERATED BY LINEAR AND SURFACE CURRENT DISTRIBUTIONS, Science in China. Series A, Mathematics, Physics, Astronomy & Technological Sciences, 36(8), 1993, pp. 998-1005
Electromagnetic (EM) missile sources have so far been limited to the c
ases where the spatial distribution of current density is either a str
aight line or a circular disk or a rectangle. It may then be questione
d whether an arbitrary linear current distribution or an arbitrary sur
face current distribution can be used as a launcher of the EM missiles
. In this paper the above question is answered, and we have demonstrat
ed that an arbitrary linear or an arbitrary surface current distributi
on of finite size has the ability to launch an EM missile, i.e. to rea
lize slow decrease of electromagnetic energy on any axis so long as th
e axis has an intersection point with the source region, and in the ne
ighborhood of this point the spatial distributions of the current are
locally flat and Perpendicular to the axis.
