We study the near-field coupling of a pair of flux tubes embedded in agravitationally stratified environment. The mutual induction of the near-field{\it jackets} of the two flux tubes can considerably alter the scatteringproperties of the system, resulting in sizable changes in the magnitudes ofscattering coefficients and bizarre trends in the phases. The dominant lengthscale governing the induction zone turns out to be approximately half thehorizontal wave length of the incident mode, a result that fits in quitepleasantly with extant theories of scattering. Higher-$\beta$ flux tubes aremore strongly coupled than weaker ones, a consequence of the greater role thatthe near-field jacket modes play in the such tubes. We also comment on theimportance of incorporating the effects of multiple scattering when studyingthe effects of mode absorption in plage and interpreting related scatteringmeasurements. That the near-field plays such an important role in thescattering process lends encouragement to the eventual goal of observationallyresolving sub-wavelength features of flux tubes using techniques ofhelioseismology.
