A. Louie et Cl. Gardner, BOUNDS ON APERTURE COUPLING FROM RADAR AND OTHER EM PULSES, IEEE transactions on electromagnetic compatibility, 37(4), 1995, pp. 543-546
Bounds on the energy that can be transmitted through an aperture have
been calculated for a rectangular RF pulse, a damped-sine pulse and an
inverse exponential pulse. The bound obtained for the penetration of
the rectangular RF (radar) pulse is shown to be the sum of two terms;
the first representing the energy that would be transmitted if the pul
se was monochromatic and the second representing a correction for the
distribution of frequencies that results from the finite duration of t
he pulse.
