Two schemes of possible two-dimensional waveguide concepts [adapted from Pfeiffer et al. (2002BB26) and its supplemental material]. In both cases the beam is incident onto the waveguide surface with an angle of grazing incidence φv, while the grazing angle of incidence with respect to the vertical waveguide walls is φh. (a) Structure for the first successfully tested two-dimensional waveguide with a rectangular PMMA core covered at the top and at the sides with Cr layers. (b) Scheme of a proposed concept for a more efficient two-dimensional waveguide, which has the waveguide core in PMMA separated from an extended PMMA film of identical thickness by a thin vertical Cr wall.
