External optical coupling into and out of semi-infinite chains of noncontacting noble-metal nanoparticles is found to be highly directional. While strong coupling of external radiation into and out of low-attenuation surface plasmon polaritons (PPs) in semi-infinite nanoparticle chains is predicted, the radiation patterns are quite complex indicating possible challenges in mode matching. We show that a treatment that neglects end effects provides an entirely inadequate description of both the PPs on the chain and of the scattered electromagnetic radiation.

  26. Equation can be formally exactly solved by means of the Wiener-Hopf technique . The evaluation of the requisite contour integrals, however, eludes the authors who suspect that they are indeed intractable. In passing, it is conjectured that a closed-form solution is indeed attainable in the long-wavelength limit κd, kzd≪1. This is left as an exercise for the interested reader. While such a result is likely to be of limited quantitative utility for practical NPCs, it may provide deeper physical insight into the details of coupling to the semi-infinite structures.
