Theory of surface plasmon polaritons in truncated superlattices
A36 identified. In the impact collision mode of ion scattering spectroscopy v, ith a scattering angle ~9"- 164 °, the shape of the shadow cone can be determined. These experimental shadow cone radii agree over a wide range of parameters well with calculations using a T h o m a s - F e r m i Moliere potential with a reduced screening length.

Play,its Department, Brown Universio', Proz,ldence, Rhode Island 02912, USA Received 5 August 1985; accepted for publication 26 September 1985 A theoretical investigation has been made of surface plasmon polariton modes in truncated superlattices using a local theory with retardation. The modes are characterized by electric fields that decay exponentially away from each interface and that have an envelope that decays exponentially away from the end of the truncated superlattice. A criterion for the existence of the surface modes is developed. Numerical results are presented for several illustrative cases.
