is a discrete set of angles of incidence and observation for which the intensity of a
nonspecular diffuse P-… We study the scattering of polarized light from a thin dielectric slab
with a dielectric constant ∊ > 1 deposited upon a perfectly conducting substrate z ≤ −d. The
vacuum–dielectric interface of the slab is a slightly rough random surface with small slopes,
and its characteristic deviation h from an average plane z = 0 is small compared with the …
