Far field scattering at low frequencies

Applied Scientific Research Aims and scope Submit manuscript

Summary

An explicit formula is derived expressing the low frequency expansion of the far field coefficient for any radiating electromagnetic field in terms of the low frequency expansion of the near field. It is shown that a knowledge of a given number of near field terms suffices to determine the same number of far field terms, thus disproving the previously held contention that p+1 near field terms were needed to determine p far field terms.
