Query: Full resonant transmission of semi-guided planar waves through slab
  waveguide steps at oblique incidence   Sheets of slab waveguides with sharp corners are investigated. By means of
rigorous numerical experiments, we look at oblique incidence of semi-guided
plane waves. Radiation losses vanish beyond a certain critical angle of
incidence. One can thus realize lossless propagation through 90-degree corner
configurations, where the remaining guided waves are still subject to
pronounced reflection and polarization conversion. A system of two corners can
be viewed as a structure akin to a Fabry-Perot-interferometer. By adjusting the
distance between the two partial reflectors, here the 90-degree corners, one
identifies step-like configurations that transmit the semi-guided plane waves
without radiation losses, and virtually without reflections. Simulations of
semi-guided beams with in-plane wide Gaussian profiles show that the effect
survives in a true 3-D framework.
