Leaky modes of a left-handed slab

Résumé

We show that there are two types of leaky modes in a left-handed slab (i) leaky slab modes which are always backward and (ii) leaky surface plasmons which may be forward or backward. The propagation direction of these modes are studied using complex plane analysis. The fact that slab modes are backward explains several previously reported results concerning lateral shifts. The complex plane analysis is shown to be particularly relevant for the study of this structure.
