Scattering by a slab: an exact calculation
(851K, LaTeX 2e with 5 PS Figures)
ABSTRACT. The model consists of an infinite number of point interactions
distributed periodically on a finite number of parallel planes. Exact
formulas for the transmission coefficients are given. Numerical
behavior is presented, first in the case the incident plane wave
has a wave vector perpendicular to the planes and then for some
tilted directions. For some values of the interaction parameter the
reflection coefficient is close to one for a relatively large set of
