The transmission of a wave through a randomly chosen `pile of plates' typically decreases expo-
nentially with the number of plates, a phenomenon closely related to Anderson localisation. In ap-
parent contradiction we construct disordered planar permittivity pro les which are complex-valued
(i.e. have reactive and dissipative properties) that appear to vary randomly with position, yet are
one-way re
ectionless for all angles of incidence and exhibit a transmission coe cient of unity. In
addition to these complex-valued 'random' planar permittivity pro les, we construct a family of
real-valued, two-way re
ectionless and perfectly transmitting disordered permittivity pro les that
function only for a single angle of incidence and a narrow frequency range.
