Abstract
It is shown that the scattered fields are almost space bandlimited functions. The effective bandwidth
is introduced and evaluated for a very general scattering system, as well as the error made using functions bandlimited to
for representing the scattered field. The effective bandwidth is very simply related to the maximum dimension of the scattering system; the error drops to negligible values for modest increases of
compared to
, in the case of large scatterers. Important consequences of the above general results are finally stressed.
